UE5 Damage Calculation System | Burn, Chill Resistance & Elemental Weapons (GAS Deep Dive) | EP 81

Learn how to build a flexible damage system with resistances, buffs, and debuffs using Unreal Engine's Gameplay Ability System (GAS).

In this tutorial, we extend our existing GAS damage system by introducing elemental resistances (Burn, Poison, Chill) and calculating damage dynamically using Execution Calculations. You'll also learn how to create buffs and debuffs, apply periodic gameplay effects, and use gameplay tags to detect damage types.

By the end of the video, you'll know how to create advanced combat mechanics such as burning weapons, anti-burn buffs, and stacked gameplay effects — all powered by GAS.

This is part of an Unreal Engine Gameplay Ability System tutorial series focused on building scalable RPG-style combat systems.
