Arcane Study synergy

The synergy increases both linked branches; it does not create a separate bonus outside their normal limits.

Skill points are earned within this skill. Rank and parent requirements apply; the skill's shared branch-power cap still applies.

Spend points from this skill's own earned budget. A non-synergy node has up to five ranks. Each rank requires the preceding rank. Child nodes require parent rank 3. Total spent cannot exceed skill level minus one. Maximum branch power = min(5, level − 1) + 2 × min(5, 1 + floor((level − 20)/5)) from level 20 + 4 × min(5, 1 + floor((level − 50)/10)) from level 50.
