he can be killed.. but it's really hard I'm sure. first of all his weakness is really long cooldown, the shortest skill at level 10 need 6 turn cooldown (Primordial Man/Avatar) and the other two need 8 turns cooldown. the skill cooldown for 3rd skill is shared.. just like Dr. Jekyll. I can change him to Caster but lorewise he's a ruler through and through..

I'm always trying to make not too OP servant, his HP is around Saint Martha or usual SR so it's possible to kill him, and his NP while seems OP are hard to use in some sense. the idea of these two is " Balance Deity"  Nara is offensive oriented, Narayana is defensive oriented since he's God of preserverance avatar. as Nara you hit hard but can't tank for party, if you switch to Narayana you can't hit hard but you'll be goddamn tough, basically he's versatile but you can't have everything at once. not to mention I made their deck to QQABB so they're suck at gaining NP thus you can't really switch around as you please.

While he seems OP on paper, I designed him so we need to read at least 2 to 3 turns ahead to use him properly,, to use party invul you need to become Narayana, to become Narayana you need one turn hence you need to avoid to use 3rd skill and use NP when enemy are still one bar away to their NP.. or if you're confident you can kill the enemy then use 3rd skill and NP at the cost you can't do anymore burst damage till you use NP once more, thus for high HP boss, not using NP might be better choice since Nara is geared for Burst hitter.. but if you wanna tank then switching to Narayana is better choice... anyway it's fun multipurpose tool .. like most of my creation so far. dry laugh
