Extensions
Extensions are the per-character skill tree — learned with credits (level 1) and EP (later levels), gated by prerequisites. See Character for the character window this tree lives in. The spark extensions (the passive specialization lines) have their own diagram on the Sparks page.
Main categories
The 15 categories at a glance: one box per category (extension count, entry points without prerequisites, rank range), left to right by starting rank, and an arrow for every cross-category prerequisite (hover an arrow for the exact requirements) — which categories open up which. Click a box to jump to that category's cards below. The spark extensions sit outside this diagram (no prerequisites of their own) — their bundle diagram is on the Sparks page. Scroll over the diagram to zoom, drag to pan, and use the ⟲ button to reset.
Extensions by category
One section per category, one card per extension. Price is the level-1 credit cost (later levels cost EP only). Prerequisites are the extensions (and minimum level) to learn first. Inactive entries are not offered by the current server build.
