Yeah theres alot of possbilities
Have a look at all the skills and see what can work together and if anything sparks your fancy
That alchemy idea throwing greater explosions and greater conflags sounds quite cool. With GM Alchemy and 50% Enhance potions the greater explosion pots will deal a fair bit of damage. You can further this by taking up Necro as well and using the corpse skin spell to lower their fire resist thus do more damage.
There used to be Necro tamers that ran around with 2 Fire steeds. Fire steeds dont cast spells but they have firebreath and hit very hard doing 20% Physical, 80% Fire damage. They also have Equine pack bonus so when used as a 2 have a 25% damage increase together. So necros used to corpse skin targets and set the 2 fire steeds on the target and they dished out alot of damage. I think some of the old necro tamers even managed to fit Discord barding skill on their template and discorded their targets to make this combo even more effective.
After saying all this to you, this template might see a return with the new taming changes depending on how well they are implemented. Fire steeds are 2 slots so you could train 1 to 3 slots and run with a normal 2 slot one. Or even just train one fire steed up to 5 slots providing their damage etc increases with the new taming changes. Infact i might want to try that idea myself when new taming changes come in lol. A necro alchemy tamer running around with 5 slot fire steed, corpse skin, explosion potions with 50% Enhance potions. Could be fun
Few months back I created a tamer PvP char based around my Pet Imps, I have changed him into a different character now PURELY for the fact im brand new to fel PvP and he simply had too many macros to consider in PvP and i ended up just panicking, face planting my keyboard and then the floor all the time lol. The template had potential though and if i was any good could of probaly worked.
But my thought process for the whole thing was:
-My mind was set building a template around these two Imps which i had spent alot of gold on and fully trained. So I created my character IMP MY RIDE and named my imps Westwood and Xzibit lol.
-Now Imps have pack bonus that also effects the damage of their spells, so the first skill i chose for the template was spellweaving for the summon Fiend spell (Which you have to do a quest to get). Summon fiend summons temporary untrained 1 slot Imps. So then using this id have 3 Imps out on the field with 50% Damage increase pack bonus on their spells. Imps cast like crazy to against targets running and my 2 tamed ones were fully GM Eval and Magery.
-Now with 2 tamed Imps and a summoned Imp thats all 5 of my control slots taken up so I can't be mounted; I need to be able to dismount. So I picked Archery and tactics for the ranged dismount with heavy X bow then switch to repeating crossbow with hit spells on it for fast firing moving shot special. Lets face it once you've dismounted someone and set 3 Imps on them they are gonna be running in the opposite direction.
-It was at this point i realised that my character; instead of being built around hard high damaging combos or specials, that he is based upon LOTS of fast small damage bursts from different sources that just overwhelm someone. You've got 3 Imps all casting spells fast at the target, then me with my hit spell repeating crossbow at max swing speed moving shotting you. I thought to myself how can i improve this for more bursts of damage, I did consider alchemy for throwng explosions at this point but they are not reliable for hitting moving targets. Then when looking at different skill spells I came across the gem that is Spell Plague which while in effect has a chance to do a damage burst to a target whenever they take damage from something. 3 Imps casting on you and me shooting you, that spell plague is bound to pop off twice. So I took up mysticism with focus for my last skills on the template. Then also realised a bit later I could also spell stone the mystic boulder spell to throw during the fight for even more damage and a chance to stun.
-So I ended up being a Archer/Mystic/Weaver/Tamer. My aim in combat was to spell plague, dismount, set the 3 imps on them, moving shot, spellstoned boulder then hope they die lol. Well if you were working with anyone else on your team also attacking then most times they would be dead. Obviously i had to spend little bit on the suit for this character and +Skills jewelry to fit everything on the template. Its a shame being brand new to pvp there was just too much going on with this template for me to cope with lol.
I hope this helps you in anyway possible, just wanted to show you my thought process when designing one of my templates. I like to be different and try new things, apart from Escaflowne my basic straight 120 tamer/mage and my wraith archer, most of my templates arn't popular bog standard ones.
I usually get an idea and then build template from ground up around that idea; like my main pvp'er Pablo Escabear who i created after IMP MY RIDE, i built this guy all around the Force of Nature Gnarled and Wild staff special move. He is a Macer/Bush/Parry/Necro who runs around with a big gnarled staff hitting people on the head, the whole template was built to make that special move do as much damage as possible, which i can hit alot of people for half their health in one hit.
Then I have Archaflowne who is a Wrestling Parry Battle Tinker, My idea for him was I just always wanted a char that used Alchemical bracers of detruction and punched stuff. With him I built his template around his punches doing as much damage as possible with wrestling mastery, skills, Alchemical bracers etc. Then he runs around with a Kotl automaton attacking stuff, I stand ontop of monster as i have shield with 120 parry so i don't have to repair the Kotl as much, when i nearly die i jumped under my Kotl automaton and repair him as he gets hit. Before this template i did make a necro Horrific Beast Form parry wrestler which was very fun, but being the massive Pet class fanboy i am, as soon as Kotl Automatons came out I changed to this template idea.
I have Bardaflowne who is my Mystic/Weaver/Mage/Bard who soulstones between the 3 bard skills. When i first made Escaflowne he was a bard and I used to love making monsters attack eachother and at this point I had never tried spellweaving which again as a pet class fanboy has the dryad allure spell. So I created this character. This character also has a combo that rocks against bosses at the end, an improved word of death combo. Basically I have an SDI suit on this character with 106 SDI or something, I then take discord as my bard skill and discord Mastery. When Boss is getting to word of death health level, I cast Arcane empowerment to increase my SDI Further, then cast the Discord Mastery Tribulation on the boss that when the target is hit by a damage source, if tribulation prots it deals a burst of damage thats like 40% of the initial damage the target took. So other week I was doing Scalis, hit him for 700 with word of death, as I did that Tribulation kicked in and did an extra 250 damage on top of that so I hit scalis for over 1,000.
Anyone who knows me on Europa knows im Bear crazy, At the Europa Brit Meet my friend Barian gave me the name Bear Grills so I built my second PvP char with that name. He is a Swords/Ninja/Stealth/Poisoner. I run around in a Chefs Hat, Full Apron with Poisoned Cleaver in my fel guild 'Fel's Kitchen [CH3F], then i leave engraved food at the corpse of anyone i managed to kill taunting them lol.
The character im working on right now and training is named Grobu. I always wanted to make a char thats in bear form constantly, So i started on him with 70 magery to run around polymorphed as black bear constantly and built him up from there. He is a Fencing/Spellweaving/Ninja who when ready will Dryad allure a Trogoldyte who i will rename 'Lurg' to run around with him and help fight. Troglodytes also heal you like a Cu Sidhe so will help attack and heal in battle. I took fencing to use the Tekagi claws weapon and Ninja to use the Dual Wield special move on that weapon. Will use Spellweaving mastery mana shield on him and Bestial armour set to make him tanky too. The Dual Wield will let me attack twice at once and with high life leech Tekagi claws it will make the life leech hit twice. So this char is built heavily around his suit as well as his template.
ANYWAY to summarise before i full on went off on a rant. I find focusing on an idea whether it be a char theme, certain pet to use, special move, spell combo or skill you've always wanted to try; Its a good place to start to build a template from. Also one last note which may help, when Im creating a char template I go on UO Guide and just look at the UO skill list on there for a while to see all the skills and what I could have together etc. I apologise for the wall of text lol
