[ghost]

• player/monster summons don't move (https://github.com/TwistedScorpio/Nostalrius/commit/87ba59c649bf38507898a39253b3b7469396474f) - fixed

• spell visual wrong order? https://imgur.com/a/CC4SvnQ

• cannot use runes on fields it returns 'there is not enough room'

• monster direction change - posted comment here https://github.com/TwistedScorpio/Nostalrius/commit/d1224058dd107f042e1fd1171a0b1abe0d4f1ee9#commitcomment-33169361

• your summon doesn't follow you when you have attack on it (it should follow)

• changing floors after /ghost has been activated, removes the invisible state
