Easy mode is a mage/weaver/tamer. This template can do anything. More challenging, but more fun is a chiv/archer/tamer. However, my all-time favorite tamer template is a necro/mage/tamer. Copying the following from another post:
I tend to play solo. The most self-sufficient of the templates listed above are the sampire or necro/mage/tamer. For spawns, I especially like the necro/mage/tamer: let spawn target your pet, then whither indefinitely in wraith form while healing your pet. For group fights and champs, I'd choose the templates with the highest damage output, which is probably the ABC archer or necro/mage/weaver.
That's one guy's opinion, anyway.
Necro/Mage/Tamer
120 Magery
120 Spirit Speak
110 Taming
115 Lore
105 Necro
100 Med
95 Vet
Pros
--The ideal champ spawn template: invis yourself, allow spawn to target your dragon/cu, then wither away. I can easily clear every mini-champ in the Abyss with this character without coming up for air.
--Animate dead summons do not count as summons, which means you can have a greater dragon and three additional summons
Cons
--You are essentially limited to three offensive spells: Mind Blast (cold damage against a single target), Wither (cold damage, area-of-effect spell), and Poison Strike (poison damage, area-of-effect spell)
Here's another benefit of necro/tamer: 3 skeletal dragons + 1 greater dragon = army.
My suit was constructed pre-imbuing, so I'm sure you could come up with something better nowadays. Nevertheless, I wear the following:
Artifacts - Mark of Travesty with Spirit Speak and Necromancy, Birds of Britannia, Rune Beetle Carapace, Stitcher's Mittens, Orny, Arcane Shield, Quiver of Infinity, Conjurer's Garb
Runic Items - Neck, arms, legs; -20 mage weapon
Jewelry - Ring with 15 magery, 15 taming, 3 faster cast recovery, 15 defense chance increase
