Need to do smth with Rapier.
Probably multiply charged strike range by 1,3-1,5 and do smth with special attack.
Otherwise Falchion is just better in most terms.
Special attack useful range melee only. Dmg reduction at range is so high like you shooting through water. I cant tell its useful. Ye you probably can save mate from assassin rat, explode barrel, thats all.
same range for normal and charged strikes
armor penetration vs headshot dmg. well how much of us rely on headshot dmg of melee weapons playing champion and legend? even if there are some doing so, weapon pretty much equal at headshot dmg for armored target. for 400 power WH its 9,25+9,25+12,5 = 31 for one full pattern, 10,33 per hit. I believe with almost same attack speed with charged rapier strikes its 11.25 per hit. And its not easiest thing to perform constant charged attack speed even on dummy, not talking about real fight. Reward is 0,92 dmg per hit. GG. compare non-headshot attacks it will be 5,58 per attack for falchion, and 4,25 for rapier. Reward is -1,33 per hit.
falchion have twice higher damage on the normal attacks on normal dummy.
I am lasy enough not to look at dmg spreadsheet, pretty sure its all ok there.
