How much does it heal, anyway? Is it even enough to be worth using?
The more points you spend on Summon Ghost the more powerful his healing ! So the SG heals you more 1 one turn each time he heals you (more HP recovering) !
But only spend 1 point in SG hoping he's a good help when you're already level 20 or so, it's not because it's important to keep this kind of skill updated, so to say
To be honest: I love this Summon Ghost skill most of all because of his Healing power and all the rest is extra plus (the Ghost forms a distraction like all other summons can do and use fireballs in ranged combat and NO fireballs if enemies attack the Ghost up close and personal ! Then you can see the Ghost try to defend himself by moving his arms or something like that, not sure if the Ghost is dealing damage to the enemy ... ).
But because I find the Summon Ghost important, especially playing a Priest build, I always look around me to see my Ghost and if he is under attack I always "try" to kill those who attack my Ghosty Ghost or, as a Priest, I run to my Ghost and use Fear, Blind or Charm that enemy ! It's big fun, I can asure you
!
Good luck
