1st Combat
I lost initiative somehow, I suspect he was cheating. Even though I was invisible and there was no way he could know where I was he charged straight at me because he could meta-see my figure on the battle map. He used mordenkainen's disjunction from some intelligent magic sword he "created fairly and by the rules." I lost all my buffs but then it was my turn.
I moved 5 feet, casted time stop for 7 rounds of action. I gated in 4 gold dragons and sunk into the ground ethereal.
He quit.
2nd & 3rd Combat
I won initiative both times by an incredibly huge margin.
I moved 5 feet, casted time stop for 7 rounds of action. I gated in 4 gold dragons and sunk into the ground ethereal.
He quit.
If it had been me a couple of months ago, I would have quit against the 4 dragons too. I mean, the decided on rules banned calling in buddies to help you win pretty much means you didn't sign up to beat the Monster Manual
However, that being said. I'm starting to welcome this Gate tactic used by the unimaginative shortcomings of failures. I mean, sure this Fighter guy was dumb enough to charge his opponent to cast Disjuction off his magic item - and there is at least three rule breaks in that statement btw - only to watch the Wizard fail each and every single Will Save against a magic item (
). But let's go into this Gate usage for a moment.
Specifically, fights like this are centered around who doesn't read the rules. Fighter can't see the difference between the two classes and typically is a moron. Wizard can't do anything less than cheating D&D's rules or the rules of the fight (recall ly's 1.5+ mil post? Yeah, Gate Dependant too). So lets take this aspect of favorable readings and put a positive spin on it in order to come up with a very useful counter.
Per the rules, there is nothing saying a Called creature doesn't give XP. The DMG notes Special Abilities are ignored and as you know the DMGII & MMV make it plain as day spellcasting is not a Special Ability (as if chapter 20 in the PHB wasn't enough already). Sage on the other hand goes into the method of how such a spell may or may not. Under his example, Summoning outside of combat gives XP and Calling certainly does as well, even if the monster joins you and you still have not regained the spell slot. So by RAW and by Intent, someone trying to kill you with Called creatures gives XP (through obviously battling your own is the same as sparring).
And lets take the prime example of usage. Calling a Great Wyrm Gold Dragon. The monster is obviously superior to the Wizard who summoned in all but one aspect. The Dragon is cannot be unique, unless you want Diplomacy checks with your handicap of interrupting this creature's life to fight for you (ie dragon eats you). This nameless stat-sheet-less is a hobbled together monstrosity of DM notes, and not the all powerful super dragon currently under the effect of 27 spell buffs with 19 specific magical items. For an ubercharger, it's a single attack source of XP that is intrinsically weaker than the PC ran Wizard.
So how much XP?
Per the 3.5 DMG (not the 3.0 ELH) the CR 27 TD with worth 64,000XP. Since leveling once per session is a suggestion and a metagame aspect rather than any real rules. If we are to continue this simulation fantasy game the creature that killed the Called Dragon needs to level. They are now a 23rd level Character, which is enough to obtain to Epic Feats and gain some cool Class related Special Abilities. In contrast, the Spellcaster, under a standardized and very much mentioned no extra XP rule, is 19th level which caused further sacrifice of Spells Per Day and Class Abilities (such as that indigo veil).
TL;DR: Called creatures gives XP because A) RAW is silent and B) GAME RULES -> FAQ says so. Gating a creature in costs you XP lowering your level which makes you voluntarily give up stuff you like while in the same action potentially giving your opponent a chance to go up to three levels during combat. Which creates this four level gap between the two of you.
