Mystic weapon mastery and enchant

Mervyn

not sure if this is working as intended.

the mysticism spell “enchant” and mysticism mastery “mystic weapon” have properties added to the weapon, however this gets removed before the spell timer is up when the weapon gets disarmed (normally involuntarily)
makes the spell/mastery pretty useless.

expected result: for the spell to remain until the timer runs out regardless of what weapon is armed or gets disarmed?

same is true for immoliating weapon (spell weaving),

Necromancy's curse weapon appears to be working correctly and retains the buff on disarm

(ninjitsu's focus attack loses the property on disarm, however this i'm sure is as intended as it works differently - no buff, just lasts for next hit like a weapon special proc which all weapon special procs are lost on disarm)
