Guild Wars 2

Curious as to what counts as a “use” of basilisk venom, while in sPvP ive been noticing BV not triggering against enemies so I started watching the buff on myself more closely. Is it working as intended if each of these situations remove the venom buff from me:

1. Dodge while having the caltrops on dodge trait equipped, removes and applies effect to noone. (Happens while just using skill caltrops as well).
2. Casting signet of shadows on an enemy, regardless of hitting target or not buff is removed and target does not suffer venom effect.
3. Many other skill uses such as infiltrators arrow, teleports etc.

One last point, while having the trait for an additional strike on venoms all of these examples remove both charges for some reason making me believe these are bugs, for example, cast BV( 2 strikes remaining), dodge one time, ( 0 strikes remaining). Or cast BV (2 strikes remaining), cast SoS (0 strikes remaining).

Are these working as intended and after casting it your next move NEEDS to be a hit or just bug fixes?

TLDR; Why does using almost any non attack skill or dodging remove basilisk venom entirely??

Blinding Powder makes us lose BV, and I think it happens with Shadow Refuge too, if “Going stealth blinds nearby foes” trait is equiped

would love to hear from a dev if this is bugged or working as intended =\
