question regarding sod damage (in General)

i just want to make sure i understand how the sod damage and reduction works on my team. since my opponent dispelled my steel skin, i am left with 422 ac which would be about 70 percent damage reduction on tankwall. my robf is on my rogue character. the fightlog follows:

is the damage for the whole team set by the damage dealt to tankwall when he is the first target and does the robf sod damage reduction affect the whole team or just rogue?

the damage is set by the damage dealt to tankwall before damage reduction.

so since SoD damage is 30% splash and you have roughly 70% damage reduction, that's why the damage values are similar.

robf is just the wearer, so that's why rogue takes less than everyone else.

ok, so when it says the robf damage reduction only affects direct hits, that means it will reduce splash damage but only on the wearer. that part in the wiki where it says direct hits is misleading then as i thought it meant it wouldn't help with splash.

well, the splash damage is directly hitting your rogue? ;)

the wording is bad but basically means the robf only affects the wearer, and only from the splash damage.

so you don't get reduced sod damage if you're the primary target, and you don't reduce the splash on your other minions.
