I don't see how the buff could be a problem?yea i think you need a different buff, it seems that you are using the same one for both of them?
Order strings don't matter. Base it off another summon ability such as hawk, scout (owl?), summon water elemental, wards, ...
Well, try it? I mean, you try a different buff but you don't try a different ability? Base it of summon water elemental and then thank me for solving your problem...I dont see how this could help.
