I don't understand the obsession with restricting offensive actions but that is just me, I'm half surprised you're allowed to make attacks when you have Shadow Clones out the way this community makes rules. Who likes combination jutsu? Apparently only me!
Anyway, I think it should be more specific and say you can control the beast with Sharingan Genjutsu or the Rinnegan like Obito did and that is all. Not any old bloke can control a bijuu with a simple Genjutsu or they'd be no threat.
I would rather just state a powerful genjutsu. Limiting it to just sharingan and Rinnegan seems like a class limiter as to who can have the tailed beast as a summon.
And regarding that, I like combination attacks too (I do them with my summon all the time) but limitations tend to be put on things of that sort because the partner is a tailed beast or Edo zombie. Shadow clones can be rather easily dispelled in comparison. Really, you can still do defensive combination techniques.
I think everyone lost interest in the rules update before we got to deal with the summons issue. Last time I spot checked myself I was against doing the summons thing. *shrugs* But then I don't host...But Trev was wondering how this would be handled as you can see back here on September 7th.
I haven't been reading too carefully, so forgive me if this has been addressed, but are we throwing out the tailed beast as summons concept? I know most players don't take that route, but it was an option.
But it looks like the discussion went on concerning what to do about challenges for a summons.
This is from the set of rules concerning RP fights. But it was never fully approved.
◾ (Pending Approval) Or, a tailed beast may be treated as a summon of the user. However, control of the beast must be maintained via genjutsu, and the user is only capable of defensive moves while the beast is active. In order to lose possession of the tailed beast, the user must have their contract nullified, control lost of the tailed beast, and/or have the beast sealed by someone else.
I had been under the impression that using the tailed beasts as summons was not an option under the jinch challenge rules. The rules, in that light, are not at all contradictory unless you refer to the contradiction between "Must be in jinchurikii" and "If not sealed within a jinch", which could be interpreted as giving leeway on the "must" in case there is a challenge list that needs fulfillment.
I suppose looking at it now, the rules are a little confusing in that regard, but I don't see any implication that using the beasts as summons was still permitted by the die-down of the discussion.
