Effect

Burning

A Burning creature takes 1d4 Fire damage each turn.

Stage 2 · Reading the situationElements and terrain

Taking Fire damage once is different from having Burning remain on you. Leaving the flames does not necessarily remove an existing condition.

Wet and Help are among the ways to remove Burning. Move away from a persistent fire surface as well, or it may affect you again.

    Effect

    Acid

    The Acid condition reduces Armour Class by 2.

    Stage 2 · Reading the situationElements and terrain

    Lower Armour Class makes attacks more likely to hit. The condition itself should not be assumed to deal Acid damage every turn.

    Acid damage, an acid surface, and the Acid condition are related but distinct. Read which of them a spell or surface produces.

      Effect

      Chilled

      Chilled grants Vulnerability to Cold damage and Resistance to Fire damage.

      Stage 3 · Combining effectsElements and terrain

      Chilled and Wet share Cold Vulnerability. Combining them does not multiply that Vulnerability twice for quadruple damage.

      Applying Wet after Chilled can produce Frozen. The order of the two conditions matters.
