Barbarian's STR and CON Saving Throws plus Gnome's INT, WIS, and CHA saving throws and Lv 2 unlocking Danger sense adding good at DEX Saving throws = Small but terrible
When a creature enters a space containing a d4 it must make a DC 5 DEX saving through. If the creature isn't wearing shoes they roll with disadvantage. The DC increases by 1 for each extra d4 in the space.
