My character summons the cat familiar. The cat familiar tries to use swap master, only to find out that the master is not within the range of that ability.
Issues
1) the ability does not specify the range.
2) the ability still uses up the ap and puts the skill on cooldown, so no repositioning the cat to try again.
3) Despite issue 1 you can't easily guess the range. The summoner didn't move after she summoned the cat, neither did the cat and the cat was on higher elevation. Still she was out of range.

Solutions:
Remove the range limitation OR change the range to the standard field of vision range for most skills AND/OR list the range in the skill description AND do not have the skill (or any skill for that matter) use up ap and be put on cooldown if you click on it but cannot use it.

PS: Is this sub-forum for issues like these or is that the technical problems sub-forum?
