Here's one of the shots anyway (half-sized) ->I was pretty happy about that

I didn't use Spiteful Spirit in that boss fight at all by the way, just Insidious Parasite and Plague Touch. He sets you on fire when he takes damage from SS or wanding, which is why I didn't use SS, but the IP lifesteal doesn't trigger it. So, when you want to set him on fire just wand him once and hit Plague Touch

Plague Touch is also great against Wild Growths and Rotting Titans
Rotting Titans I fought with 455 life and no enchants, and I fought them on their own
I learned later I could have Mending up without them hitting me with Lingering Curse (full ench strip) if I kept Plague Touching their Rotting Flesh spell - they get really obsessed with casting Rotting Flesh over and over exhausting their energy. Kill them with IP, wanding, and SS if you have the energy. They spawn a L24 Wild Growth when they die (which itself will spawn 3 L24 Titans when it dies...).Wild Growths need line of sight to hit you with their attacks, so if you're fighting 1-on-1 you can use terrain to stop them hitting you. Then when you're safe, remove all your enchants to get your 4pips of energy regen and kill them with SS by itself
If they have other titans with them though, you might have enough energy just to fight them normally - plague touch the poison back onto them, cast SS and IP, wand them, keep healing breeze up if you need it and they will drop. They spawn 3 L24 Titans when they die (1 earth, wind and water titan)One last note is on Water Titans - these guys are pretty much my highest priority to kill because of Maelstrom, 10s of aoe spell interrupt. If you see one casting Maelstrom (you will see it summoning a large glittering ice crystal out of the earth), either top up PS and HB just before it finishes its cast, or jog out of the area the instant it casts - you may be snared at the time so be careful! If you have a fresh PS and HB though, you can just use Maelstroms to regen energy

Well, there you go

Sadly it's not a repeatable quest it seems, but I still have Kryta Titans to kill
