i can't for the life of me find anywhere where it mentions how regular magic summoners and ki seal summoners effect each other, (ki seal summoning is fleshed out in dominus exxet). the only problem i'm really having is what happens if a ki seal user summons a monster and a magic summoner want to control or banish it, especially since the two ways of summoning work very different.
i'm thinking of working it one of two ways, and i'm having some trouble deciding which would be more balanced, though i may just toss together some homebrew rules involving some new mechanics, but that seems too dodgey.
idea 1) MK checks; when any conflicting checks with another summoner is required the ki seal user simply makes an MK check using their total martial knowledge score in place of the relevant summoning score. in this case a ki seal user could not initiate a bind, control, or banish check, only defend against one. but they could attempt a summon check by invoking their seals for that creature, then making an MK check against the summoners ability, and then the usual what-have-you ensues.
idea 2) ki sealers are bastards; when in conflict with a regular summoner the ki user has no method of mystically combating the offender, the creature is not technically considered summoned and the magic summoner would have to go about exerting their will upon the creature as if it were not summoned but their of its own will.
i dunno, what do you guys think.
