Hey, yet another question. How is cooldown length calculated in the tick-based combat system? I'm trying to develop a simple combat simulator to develop the most effective ability rotations in certain scenarios, but I'm not sure how long a '10 second' (for example) cooldown really is. Is it 16 or 17 ticks? Many abilities align their cooldown on multiples of ticks, but things like Snipe, Firebreath, Needle Strike... don't, so I'm not sure if they round up or down.

Knowing Jagex, some of them round down and some round up. Might be best to just count yourself.

Yeah, that sort of thing is up to the developer. Another option is that sometimes it's 17 ticks and sometimes it's 16, so that they average out to 10 seconds. Fun.

Thanks. In my calculator, I adjusted it for the worst-case scenario which is rounding up (e.g., 5 seconds is 9 ticks, or 5.4 seconds). Doesn't affect the result too much, but it's better safe than sorry I think.

Threw my ability data (most of it was gathered by Brunokiller) into this paste:

It says that it rounds up to 17 ticks, but I'm not sure how rigorously that was tested
