Losing an enchantment

When a skill description says something like "Lose one enchantment.Bla bla bla..." , is the enchantment lost picked at random OR do we choose which enchantment to lose OR the latest enchantment casted on us get removed ?

i havent played derv but i did some test with melonni. i noticed that if u put [skill]zealous renewal[/skill] and [skill]twin moon sweep[/skill] on the same build, the former get removed after few seconds, becoz the hero applying the latter .... defeating the purpose of casting the zealous renewal in the first place...

anyone..?

ever played magic? farmiliar with the term "the stack". the stack is basically all effects currently in play. same applies to guild wars conditions, enchantments, and hexs. the latest one cast is at the top of the stack and the first removed.

so the last one cast. same goes for condition and hex removal, for future reference.

aaahhhh.... thanx...
