The skill/buff description of Half-assimilate (850155) is wrong since it says
Transforms a portion of your body into a Kulech, blocking damage from the next attack for (Buff0-Time) seconds. When the effect ends, you will receive the [622389] effect, increasing [SC_SKILLTIPS_HEAL] by (Buff0-622389)% for (Buff-Time-622389) seconds.
The issue is that it says 5% for 50 seconds but in fact it is 50% for 5 seconds.
That means that (Buff0-622389) needs to be change from 5 to 50 and (Buff-Time-622389) needs to be changed from 50 to 5.
