Trying to make a lawbringer build for clearing tombs. Say, what if my frenzy merc ran 2x lawbringer, paladin ran santuary with the synergies, do all these auras stack? Do i synergize my mercs aura? This is all so confusing to me.

I just want to make a good tomb runner build revolving around sanctuary if possible. Please throw me your ideas!

No it doesn't. Every unit is their own entity and they can't synergise each other.

thats true

the 2 lawbringer auras would stack tho.... what is it lvl 15? so it'd be lvl 30 wearing 2
