Lichdom: Battlemage is a first-person action game with RPG elements where the focus is centered around casting and combining different spells. The player is given control of an mage with infinite power that can cast spells without any need of mana or rest.

The player can choose between three sigils (spell schools) at any given time. Each sigil has three type of spells: a missile attack, a nova attack and a long range AOE attack. Each attack can be given a different effect which affects the gameplay in a different way. The three effects are: destruction (direct damage), control (various status effects that stagger or distract enemies) and mastery (debuff that increases destruction power).

Along the three different sigils the player is equipped with a shield that also comes in three flavors: agile (unlimited teleportation, for quick combat), strategic (balanced, with the possibility of blocking attacks) and tactical (focused of blocking attacks). Each shield type offers a reduction in the time to cast a different attack type based on it's specifics.

The game also features a basic crafting mechanic where the player can combine different spells in order to produce better variants of the base effect. The system features actions like crafting new spells, upgrading existing spells, retrieving components from previous crafts and even a gambling system for those who wish to test their luck.

Based on the player's choice of gender, the story is told in a specific way that revolves around the character's personality. The story remains mostly the same but the roles of the two characters are swapped out. The story is rather generic and revolves around the dragon (the spellcaster) and the gryphon (the scout) who seek revenge after the cult of Malthus killed his wife and took her sister.
