Lumos
Planned feature
Light nearby space with your wand. Lumos uses cooldowns, not mana.
Discover it, then study
Personally craft a torch. This is intended to produce a discovery popup and public chat announcement, not silently grant a learned spell. Study at the Spell Bench with one charcoal; initial learning costs no XP levels. There is no learned-spell predecessor.
What it helps you do
Lumos enables a bounded light-source mode with a visible wand glow. Useful illumination is required; particles alone or shader-only dynamic lighting are not the promised result. Intended upgrade directions are a stationary light or a short revealing pulse.
Cooldowns, limits and refusal
Its toggle cooldown is 2 seconds. Activating costs normal eligible wand wear; turning it off costs no condition and is not a protection-charge farming action. Light must respect protection and leave no damaged world blocks. Glimmer is not another name for this planned launch spell.
Study and upgrade materials
Learn Lumos at the Spell Bench with one charcoal and no initial XP-level cost. Personally crafting a torch discovers it; the torch is not the study fee. Upgrade material family: binding. See Discovering and learning magic in the related guides for XP-level costs and learning tiers. Exact upgrade recipes and specialization-change materials are still undecided for each spell. The upgrade ideas above are not complete recipes.
