Epic bonus to DC from cores (Primal, Draconic, Exalted etc.)

[Arctigis]

The 'spell casting' destinies all state the following benefit from the cores:

+1 Epic bonus to all spell DCs

This +1 increase is not reflected in any of the tooltips for spells (L29 Sorc). Is the tooltip
broken, is the +1 DC not working or have I misunderstood what this means?

After resetting all my ED it appears to be updating correctly.

Previous to resetting all my ED post U54 it was not reflecting epic destiny bonuses in the toolbar or in the character sheet.

Correct, the core DC bonuses don't stack between the trees, so that you're not "missing out" if you dip into non-caster trees.
Likely-wise, the individual spell DCs in the tree don't stack so that you can more easily branch into other spell schools, without "missing out" on DCs for your primary school.

It's probably this (not stacking) - thanks!.
