What type of damage should I put on my weapons? Is the Dino slayer armor at all workable into a suit? Can the turtle itself even be soloed in any decent amount of time?
Ive been playing with this a lot recently, this is my personal advice. Take it or leave it.
When I use a FIRE damage weapon, ENERGY is also fine and marginally better for some of the mobs, I just couldn't be bothered making one, the difference is trivial.
Stage 1
100% FIRE double axe with fire area, whirlwind till your fingers bleed
Stage 2
100% FIRE double axe with fire area, EOO the tigers be careful of the gorillas, if there are more than 5+ gorillas in your attack range and you only damage and not kill them be prepared to get banana'ed to death. I usually single target the gorillas and round up the tigers.
Stage 3
Very awkward phase, I usually start by honoring myself (5 mins) and take out all the remaining tigers as they are a pain and can do a huge amount of damage and drop you quickly combined with the Infernus and Phoenix. I switch to a 100% FIRE double axe WITHOUT area effect to do this.
After the Tigers are gone I switch to a 100% COLD damage Elemental slayer. EOO the Greater Phoenix and whirlwind till your fingers bleed. Just be careful to move out of fire patches from the infernus, they will strip health off you fast but with the Elemental Slayer they usally die in 2 swings. (I tried equipping a bird slayer talisman, It didn't work /sadface)
Stage 4
I do this on foot, leave my swampie out of the way and use a Reptile Slayer Bladed staff (AI) and usually throw Valor at the altar. You literally have to take 1 at a time in this phase. The dinos have fairly high resists, lots of health (hence switching to AI with bladed staff) and they dismount AND disarm you often. WW is not an option in my opinion. I usually EOO the Allosaurus as they have the largest health pool, the Dimetrosaur don't hit as hard and have much less health.
Both dino types have the dismount, disarm and AoE poison effect.
The Dragon Turtle
I personally use 100% ML, 66% LL, 50% SL, 40% LA, 40% LD bladed staff, AI till its dead. Something similar would be fine.
Need to be wary of its dismount and disarm abilities, I've had both happen on one occasion and it does not end well.
The 'sphere' phase is good, it's a break from all direct damage and I welcome it.
The only thing to add to this is what i call the 'hit anomally', sometimes you will literally miss every swing and when you do hit your damage is halved (and no this is NOT the debuff applied by the boss with the turtle head icon). You just need to push through this, eventually your hit chance will increase 99% and your damage will double.
If all goes well I average about 50 mins for this spawn. I usually do this in Fel, it's quieter than the Eodon spawn. Loot and head home for tea and medals!
