Well the way to purify ur doom wep is easy...well quests are not...wat u do: All artix quests must be finished (in necropolis) and then u click purify doom weapon after u baught it...simple answer ...
u gotta purify a doom weapon then upgrade it u purify and upgrade your destiny weapons at necropolis
It is Light beacon but if you have money it is The doom sword thing from the mysterious stranger.
yes they are good because the do huge damage and go to artix to purify them into light elment and you can upgrade the purified doom weapons but you need a dragon amulet to weild them if you do.
if you eant a a destiny weapon
go on one of artix's random quest to where sir malafc quest is
You can get powerful weapons in lots of ways. Theres doom weapons, Sir Koffagus, Sir Jing, etc. You do not need the Dragon Amulet for the original doom weapons.
advice: get a weapon
If you mean the doom weapons, it's just 2 areas left of the center of falconreach (the area Twilly and Ash are in). The guy who sells you the doom weapons is wearing a grey robe, and he sells the doom weapons for 28,000 gold each.
you cant
you just use puriphy the first doom wepon
get shadowreaper of doom from mysterious stranger (Look around a bit if you can't find him) buy shadowreaper of doom, goto artix in the necropolis( in dark, foggy, purple area), travel there. (click on the weird board/sign next to ash, then press travel. You need to have completed storyline of artix. then get 10 undead slayer badges(You'll find out what these are if you do the artix quest line) and walk to artix, then click purify, or purify doom weapons, then turn in 10 undead slayer badges and bam, u have a blinding light of destiny.
the doom weapons are level 8 weapons and do lots of damage.
