Necropotence
I'm working on a series of Magic: the Gathering cards repurposed as D&D spells.Some notes on this one:* One new experiment I tried with this spell is making it both a necromancy and enchantment spell.* While "a corpse" is a cheesable material component that allows "bag of rats" t...

Feat Trees' New Roots in 5e D&D
D&D’s last three Unearthed Arcana (UA) playtest packets included tech that hasn’t been printed since past editions: feat trees.Note: You may also hear these called “feat chains,” which describes a feat tree that only has one higher-level associated option, instead of branching into several. ...

Fastball Special
On May 23, 2022, Wizards of the Coast released the Giant Options Unearthed Arcana (UA), featuring the Path of the Giant Barbarian.

Kender Aces
Yesterday, D&D released their first Unearthed Arcana in months. The Heroes of Krynn UA centers on the Dragonlance setting.Among the character options is the oft-maligned Kender race, which appears to have received a bit of retconning to their thieving ways.

The ThinkDM Monk
Hi Folks!The other night I was laying in bed and I had a "eureka!" moment about how to address some of the monk's pain points. I got up at 3 AM and put this reworked monk class together. After some workshopping with other designers, I am happy to present the rework of the core class. Thi...
