1. Set your Vantages & Affinities using the dropdowns. History sets your minimum number of lines; Destiny sets your longest line length.
2. Click "+ New Line" to begin a new line. Line 1 is your longest and must match your Elemental Affinity.
3. Click the start socket first — the Master socket (or Integral Core on older generations) — then click each outer socket in sequence to extend the line outward.
4. Click "End Line" when you are done adding sockets to the current line. This locks it and prepares a new slot.
5. Repeat for each line. You must have at least your History minimum. No line may exceed your Destiny maximum. Max 6 lines, max 6 sockets per line.
Locked sockets (colored borders) are restricted by your Martial Affinity — only Quartz of that element may be slotted there.
Line elements: Line 1 matches your Elemental Affinity and grants +1 effective rank to matching Quartz. Lines 3 and 6 are always Neutral.
