So a while back we were playing our weekly session, and there was going to be a boss encounter down the pipeline that our GM had dreamed up for us (no official adventure, this one is pure homebrew, though our GM has ran this setting multiple times and written up an ungodly amount of material for it, so it's pretty well fleshed out and quite fun).
Quick party rundown and backstory.
The party consisted of: A Human Draconic Bloodline Sorcerer, specialized in lightning magic (like 90% of his spells are lightning, though, and this is important, he does have Ray of Enfeeblement).
A Halfling Bard. She's our party healer, buffer, and resident cute. She took the archetype that lets her channel positive energy. She also like sweets.
An Elf (sea-elf) Oracle. Token evil teammate, she took the Inflict tree of spells, has the Dark Tapestry Mystery, and is quite creepy.
A Vanara Monk of the empty hand, who has an enchanted bottle that he smacks people with. It technically counts as an improvised weapon, which is why it works with the empty hand archetype, even though he carries it around and his hands most certainly aren't empty. Our GM is nice.
And my character, a Human Summoner and her Eidalon, Mr. Floofy, who takes the form of a medium-sized mangy housecat. The summoner has lots of support spells and all the summon spells, while Mr. Floofy is speced out for insane single-target damage, and he and the monk are the main damage dealers for single targets, while the other casters are adept at dealing with large groups with lightning and flamestrikes.
The situation was that we had basically accidentally opened a portal in the middle of the ocean under the waterline that lead right to the BBEG's castle (by breaking a magic item of some sort when we blew up the ship it was being shipped on with a lightning bolt to the powder storage bay). The portal closed after a few rounds of seawater pouring into BBEG's throne room.
He was not pleased.
Fast forward a few days, and we're adventuring through a temple when we encounter an assassin that has been kitted out specially to combat our group. "The Chaos Mage is displeased!" he shouts, waving a wand at Mr. Floofy. A wand of banishment. Quadruped Eidalons have an absolutely laughable will save so poof, Mr. Floofy is gone in the surprise round, and as one of our main damage dealers, that was a big thing. (I have subsequently evolved spell resistance so I have at least one layer of defense against that kind of thing)
Initiative started, I was up last. The monk, who is always first, was first. He goes in, and instead of doing his usual beat-it-in-the-face-with-as-many-ki-points-as-i-can-throw-at-it technique that the GM was probably prepared for, he did something unorthodox for us. A trip. Mr. Assassin does a faceplant, shouting that we will rue the day we flooded the Chaos Mages inner sanctum. It's at this point we notice that most of his clothes are magical, and when the Sorcerer's turn rolls around, the lightning bolt bounces harmlessly off of him. Someone remembered their rubber underwear, and he was immune to lightning, almost completely negating the sorcerer. Bard sings, swings, and misses due to critfail (it happens).
The Oracle goes, and tries out her Interstellar Void Revelation, and HEYGUESSWHAT it seems he's just straight up immune to elemental damage because immunity to cold was in his super-suit too. The oracle says she's fine with this, as nothing blocks the holy half of flamestrike. We didn't want to test to see if he somehow had a way of absorbing negative energy.
Instead of standing up and incurring AAO's from the monk and bard, the Assassin stays lying down that turn and casts defensively, passing the concentration and flinging a Hold Person from another wand at the Monk. He manages the will save though, and it goes around to my turn, with the assassin still on the ground. The GM asks what I do, since I normally buff Mr. Floofy and have him go at it, he's curious as to how I'll change my tactics. As a side note, I do not have the Summon Eidalon spell because I'm dumb.
My summoner was pissed. Her best friend had just been banished! So she does the normal thing in this situation, using the summoner ability to cast Summon Monster as a spell like ability if their Eidalon isnt up. "I summon a Succubus."
He's lying down and prone, so my newly summoned Succubus easily grapples him and starts making out. Level drain was something he was not prepared for >:D
The fight got a lot easier from there, with the Succubus draining a level every turn. What made it a cakewalk when it shouldn't have been was when the Sorcerer cast Ray of Enfeeblement and knocked 8 points of his STR. He couldn't break the grapple, and the monk was making sure he kept down even if he made a little headway. Also the Oracle had no problem flamestriking both him and the Succubus (I told her I didn't care if she damaged my summon, My character has a habit of mistreating her summons sometimes. Not Mr. Floofy though). He died due to level drain, sonic damage from the bard, and holy damage.
Long story short, my GM's boss was... less effective then he probably could have been (the GM's plan was to banish Mr Floofy, Hold the monk, and then break out the damage spells and some activated traps in the room to incapacitate us, relying on his defenses to protect him from the rest of the party. Also it turned out negative energy did actually damage him). All because the monk tripped him, basically, because after that he couldnt move. It was amusing to all of us that even though he was immune to our usual tactics, all we had to do was change up tactics just a little for it to be a compete cakewalk, even without our major damage sources.
TL;DR We stomped a boss who was immune to most our stuff because we tripped him. Does anyone else have any stories about fights that should have been tougher but wern't because of unorthodox tactics or unusual actions? Any GM's been on the receiving end of this? (I know I have, tale for another day ;) ) How about just amusing boss fights in general?
