With the advent of bound endless spells I have a few questions. Do we have to take the bound variants? If not Would it be worth it to take away certain planar buffs for what bound spells give us?
believe @Dragvindel means the realm bonuses certain endless spells get when cast in their realm of origin
They are referring to the small buffs certain spells get if you are in a particular realm. (Purple Sun gets more movement if in realm of death for example.) I would probably always pick a bound spell if it moves at all though.
Interestingly, bound chronomantic cogs are worse than regular ones, because only caster can manipulate them and only in the end of hero phase. Yes, it denies enemy intercepting it, but you pay extra 10 for it and inconveniences too.
