Just comparing Caltrops and Ice Field: Ice Field´s description gives a radius of 7,5 while there is no radius in the description of Caltrops, but it should have one listed. Ice Field has a duration (e.g. 12,1 seconds at skill 41) and Caltrops too 18,2 seconds - which is strange, as both have effects that end earlier than the spell/skill, e.g. Caltrops last 18,2 seconds but their -50% movement only 15,2 seconds - the remaining 3 seconds the Caltrops are just lazy...? My Caltrops have a "physical damage" listed which sounds fine, yet that damage is *0*...? Is there a skill needed to hurt enemies with Caltrops?
