Poison Blade

 is an active skill that can be learned by warriors at level 22 and can be ranked up at later levels.

can be performed with a pair of twin swords by the warrior to deal damage over time. This is a good skill to keep using, as it has a low cooldown (even shorter than the duration of the skill itself!). Poison damage itself quickly becomes marginal when mobs' health pool rises on high levels (past level 60), but when Edge damage this skill gives to Scythe is counted, it's actually a good damage skill.

After warrior rework in February 2017 this skill gives warrior 2 Edge over enemy. Originally this skill gave 1 Edge and other point only when noctenium was used. Poison Blade also chains to Scythe.

Do note that this skill is weakened when used in PvP. Enhancement Points can be used to raise poison damage.

Amount of damage dealt varies dependent on skill rank.

Rank table
To upgrade to the next rank, one must find a Tactics Instructor and pay a certain price of gold dependent on rank.

Glyphs
Upon learning, glyph points can be allocated on this skill. At level 60, a character has 50 glyph points available to spend on all available warrior glyphs. Most glyphs, specifically common glyphs are learned automatically, while Master Glyphs must be looted from enemies or bought at a Trade Broker.
