There's a bug in retail (there was at least till high five) in which if you /useskillforce (be it with macro or typing it), you can recast the skill a second before the cooldown finishes, before the skill clock thingy completes the cooldown cycle. (Maybe a bit sooner). It's always a static time.
This bug allows to get 0 cooldown on several skills with enough reuse buffs, because it applies the -1 second cooldown after the reuse multiplication.
Any idea how can I start looking into this?

sometimes something like this happens to me when summoning cp pots.

Does the client also check for reuse? Maybe useskillforce bypasses client check.
When editing the delay on L2Character.java

Code: Select all

 public void disableSkill(L2Skill skill, long delay)    {        if (skill == null)        {            return;        }                if (_disabledSkills == null)        {            _disabledSkills = new L2TIntObjectHashMap<>();        }                _disabledSkills.put(Integer.valueOf(skill.getReuseHashCode()), delay > 10 ? System.currentTimeMillis() + delay : Long.MAX_VALUE);    } 

Setting delay to 100ms and using useskillforce would let me spam skills, but just clicking on them wouldn't let me.
