Was levelling another warrior alt this morning and to my surprise my class 1 wood point arrow I shot with a rough hickory bow was able to injure a wilowisp!
After searching I realised this is an issue known to the players
http://www.project1999.com/forums/sh....php?p=1971150 but I couldn't find a bug report (here it is!)
Magic arrows should be required to inflict magic damage to magic npcs (whether bow is mundane or not shouldn't matter).
If this is a point of contention I will search for evidence.
