Well, I don’t think my players are here but I’ll put it in spoiler tags anyway. Those playing in a world called Yphilios, don’t expand this.
::: spoiler Frostfang’s equipment
The dragon they will have to fight, Frostfang, is an adult white dragon. But he is not your typical “huge polar bear with wings” white dragon. Frostfang found a nice little golden ring on the head of a wizard he ate that fits his claw pretty well, and this ring (Headband of Intellect) made him a lot smarter and enabled him to learn the spells from the wizard’s books (and other books that other dead wizards left behind).
In addition to the ring and the spells, he has been learning blacksmithing from an artificer he has kept captive for this purpose, and wears a breastplate made from the breastplates of all the paladins who tried to kill him. It is a Breastplate of Radiant Resistance. (There are three paladins in the party, sue me.)
He also has a Dagger of Warning. Partially because of the Warning property, and partially because this way he can cast Steel Wind Strike. Because I’m evil.
Maybe I’ll also give him a piecemaker. Lair actions are one thing, but a six-foot metal bolt flying at you at mach 3 is another.
