Kissassist may not be the best tool, to react to events.
You may want to have a look at mq2react or the new project Lem to handle fast reacts for dedicated situations.
Lem allows fast responses either to mobs-emotes expressed by recognizable text-sequences or else fast responses to dedicated conditions.
Kissassist is a great tool to handle the overall behavior of a char. In order to do all what it is able to do, it needs to process a lot of instructions per cycle. To react to specific time-critical situations usual dedicated events having only the instructions how to react to this one situation have a much better react-time down to a view milliseconds.
