As a suggestion I think it would behoove summoners to have certain abilities and features of avatars broken down so they a bit of fore knowledge what to use in certain situations
ie
Nether Blast: Ranged Single target that is very good for resistant mobs you cannot nuke very well with merit bps
Night Terror: Same features of Nether blast but not ranged, but hits harder than Nether
Somnolence: The only ward ability that does damage and heals it slightly(but it's lol and could only recommend if the other ward abilities aren't going to work and you have to keep diabolos out)
I can do a breakdown of avatars and by their abilities if you'd like and you can edit it as necessary later on but the problem because of how this job was written by a scatterbrained dev is that useful tidbits like these get lost in translation unless someone has used it and doesn't share, forgets, and/or quit.
An interesting tidbit to know also that there is a 6 second charge time for all abilities except shocksquall which is half a second.
