At QL 20, every monster gives you double XP. That would take gargoyles from ~100 to ~200 XP per kill which at ~40k XP per lvl for lvls 25-35ish would drop from ~400 kills down to about ~200 kills per lvl and you can't even have QL 20 at lvl 30.
Thought I'd bring this topic back up, now that I've reached my current goal of hitting QL level 20, with what is my new "main" game (the base build - no side choosing quests have been done yet). Not planning to level up the skill any more, although my plans in this game often change.
Now when I do those other quests, I'll get double the XP on any kills involved. Including that bridge troll. Still planning to do a bit of leveling up from the Brutes and Arulirs so I'll have some skill points saved up to use in future updates.
Ah, 4 months ago me, how naive. I just now hit level 25 of Quick Learner, and I no longer have any plans to stop. But I will take a break so I can level up the More Criticals a couple more times.
I am very very very slowly raising to Lvl 124 and then will buy my 20.th QL with this Build.
Then I may spend some skill points on other skills - if I play AT on a regular base again.
Right now I lost nearly all interest in playing AT. Honestly I feel bored at the moment. Guess that will end with a new version.
