When playing as a Warlock, after raising the base levels of both the “Demon Mastery” and “Bind Demon” skills to 20, I consistently received a system notification stating that the action was “impossible” whenever I attempted to use these skills—whether via a single click or a sustained press—on critically wounded, low-HP demonic monsters in any map zone.
I am unsure how this bug occurred; however, after I died and subsequently reset my character’s skills, the “Bind Demon” skill became unusable against both normal and Super Unique monsters in any map—regardless of whether its base skill level was 10 or 20.
The issue might be not in the skill or skill points invested but elsewhere.
I noticed that i can’t Bind Demon when the maximum number of Demons are already with me. After sending one of my lesser Demons away i could Bind Demon again.
In fact, I first used my summoned creatures to lower the monster’s HP, and then—while ensuring my summoning slots were completely empty—I attempted to use the “Bind Demon” skill. However, I was still unable to capture any demon monsters. I have no idea what the problem is.
When you are certain you got enough hard skill points invested into Bind Demon to “capture” the demon you want - 10 champs, 15 uniques, 20 supers - AND you got a free slot available, all you need to do is damage said demon while TARGET AND HOLD the button for the Bind skill. It might need a few tries depending on the bind chance but it does work.
LVL 20 Bind, with 5+. Still having hard time binding Hephasto. This is taking way to much effort for what it’s worth. Spend the points on another skill or play another toon!
