What is confirmed
The current Early Access statement lists spell crafting among the build's fully featured systems. It is presented as an existing mechanic, not merely a full-release aspiration.
The same statement says spell crafting should be fleshed out and expanded further before the full release. Version labels will therefore matter once combinations and values are documented.
What is still unknown
The official page does not publish effect names, categories, resource costs, requirements, magnitude, duration, scaling or combination rules. It also does not define how a player acquires or edits a spell.
This page therefore explains status and evidence boundaries only. It does not present sample combinations that could be mistaken for game data.
How the spell archive will be built
After release, the first pass will record the terminology the interface actually uses. Only then will the archive decide whether the system needs fields for effects, requirements, cost, magnitude, duration, skill scaling, combinations and version history.
A spell planner will come later, if the real data supports meaningful combinations. It will not launch with invented options.
