I know that there is some antipathy towards introducing many of the things we had in xi but I strongly feel that these are something that would make arch/bard a lot more fun.

Poison Arrow- additional effect poison
Sleep Arrow - additional effect sleep
Ice/fire/wind etc arrow - arrows with added elemental dmg.

Some that were bolts in xi but could equally be arrows.

Bloody bolt - additional effect hp drain
Acid bolt - weakens defense
Holy bolt- additional light dmg
Darkling bolt- additional dark dmg

Wouldn't these and/or similar be fun?
