From experiences with my alt which is 9 ps and will be 10 ps @ 9 agi.
1st always be aware that ur blocktimings must be close to perfect.
2nd is to fight in a sorrounding that fits your char e.g. hide behind corners, backstab all in all, get into close range.
Whenever you ve achieved that, never hesitate and be aggressive. High pressure on the opponent leads to mistakes that can be punished!!!
Swords: Either choose decent basespeed e.g. 2handed or heavy greatsword (recommended heavily)or completly leave them out. You are fairly slow anyways, no need to get a slow sword.
Reason is that assuming you dont attack a total noob your initial attack will be blocked and after that you will be in trouble. Greatswords are not the best solution in that case.
Maces and hammers: You cant do anything wrong with those, specially when you attack from close range or suprise your opp. -
Polearms...well, they can clearly achieve better dmg. output.
There is tools like great long axe, great long bardiche or generally speaking every polearm you d consider having good or really good dmg!!!
In general, stick with hammers and maces. Unmatched effectivity with high ps!
Sidenote: The coolest ppl. choose the spiked mace...!!!
