Sorry for spelling, english is not my first language and this spelling is a tad off thanks

So this was a character in a Champaign that had started a while back like end of 2018 to the end of 2019 Drogbeard was a mighty lvl 12 warforged barbarian, we had a undead death domain cleric which would store magic gems in his skull, we had a corgi loving warlock and a living suit of armor, now Drogbeard wasn't all that impressive aside from the fact that he was around 1000 or so years old and made of solid iron or steel, its been awhile and i lost the character sheet, how? eh magical magics i guess, anyway. Drogbeard was insane, he had and would have killed everyone in the party had he not died first, it was kinda his thing his whole backstory revolved around how he delved into madness doing random odd jobs for the king of the world and the fact that they were so gruesome sent him insane. so what happens is the party gets together through teleportation of some sort, Drogbeard just so happened to be fighting a horde of orcs for fun when he appeared half his height standing at a flat 3ft instead of a full 6ft due to the nature of the teleportation. so session 1 was just going around exploring the split universe thanks to a beholder blah blah boring background world stuff, session 2 rolls around and we get into a fight and it was just some kobolds, now this is where our undead death domain gets the fun idea to start putting gems of fireball into his skull to keep safe.... why? i have no idea but he did. session 3 rolls around and nothing major happens, and we skip a few sessions and were at level 12 and at the last session as we moved onto something else afterward as we kinda just forgot about it, sad but true. anyway, that fateful day we were chasing some kobolds and before we knew it were were surrounded by around 20 of them, oh i forgot to mention this by this time Drogbeard had a spear shaped hole through the middle oh his chest that happend in session 8 thanks to a ogre, Drogbeard has a single gem of fire ball but our undead death domain cleric however has stored 5 in his head and 14 in his bag, of course the dm has him make a save to make sure that the ones in his head are safe and he fails and gets a nat 1, which means it flys right out of his eye socket and straight into the hole in Drogbeards chest, this of course causes it to shatter and explode but right before then to protect the rest of the party the cleric grabbed Drogbeard and with sheer strength alone jumped into the 40 or so kobolds (idk if i'm spelling it right sorry) which meant that the 5 in his head exploded, the 1 in my bag to explode and the 14 in his bag to explode and not to mention the ones that the kobolds were holding if any, and well to say their was an explosion would be an understatement, it was as if someone drooped a bomb into a small and tight impact place and just the slightest movement set it off, but not just one bomb, but several bombs in the same spot all compressed into one (you get what i mean ya?) and so what was left of drogbeard the insane and the undead death domain cleric was a smoldering cloak and a pile of molten metal and a bunch of ash where the kobolds where standing, of course the rest of the party was fine just now with ptsd
