D&D’s New Free Feats Will Make You The Ultimate Edgelord At Every Table

D&D Beyond recently launched playtests for “Villainous Options,” introducing four new, free subclasses for D&D players to try. These include options like the Hellfire Domain Cleric and Hell Knight Fighter. But the playtest isn’t just about subclasses; it also includes “Paths of Villainy,” a system built around two connected sets of feats.
![Trajectory-persistent adversarial attacks reveal that recurrent state space model (RSSM) architectures amplify initial perturbations-increasing by a factor of 2.26× in the deterministic GRU world model-before GRU contraction attenuates them, a phenomenon not observed in single-step baselines, and which is mitigated through adversarial fine-tuning-reducing amplification across all steps-resulting in a reward gap of only [latex]0.000892 \pm 0.000057[/latex] at a planning horizon of 30, and demonstrating a fundamental trade-off between model expressiveness and robustness to adversarial input.](https://arxiv.org/html/2604.01346v1/x1.png)
