2h weapon choice

It's a case of carrying multiple weapons being a good idea. Empress Point is a good all round weapon but in terms of physical damage Hawke's Key if gotten at high level with the ignore armour property is better. Elemental weapons have a couple distinct advantages. 1) they ignore enemy armour by default 2) they deal double damage damage against enemy weaknesses and 3) there are more elemental damage boosting equipment then there is physical. There only downside is that on nightmare you do have to worry about enemies elemental immunities.

So there are three elemental weapons that are worth carrying around
Bloom (cold dmg), Sundering (electricity dmg), Celebrant (spirit dmg)

If your not playing on Nightmare and had to pick one to put the primeval lyrium rune on Bloom
