UE5 Combat Typing Game (pvp, 1v1)

It is necessary to implement a PC game in Unreal Engine 5 exclusively using Blueprints. The game is a 1v1 PvP duel between wizards, where spells are cast through a set of text. The player selects a spell and enters a fixed formula, with each letter affecting the cast in real time. Mistakes do not stop the action but change the result or create instability. There is a possibility of counter-spelling if we hit the right casting window of the opponent). Focus on gameplay logic, duel cycle, and correct input handling. Any 3D scenes, art, animations, or visual polish are not needed; a test map is sufficient. The game must be technically clean, extensible, and suitable for further development.
Additional documentation will be provided at the beginning of development.
