This doesn't seem to be the case.
Spoilered for bigSpoiler: show
I went and tested on Ironclad Cleaver(spams seismic impact.) Again, .409 earth resist+326 magic evasion and a 500 skill bar petrify.
In 12 Seismic Impacts terror never landed.
Ard even got hit with only barspell+102 M.eva, and he resisted terror too. It wasn't until I canceled his barstone that terror could land.
I think it's possible that there's a difference between direct Terror inflicting WS, and terror as an additional effect. Because in the case of Seismic Impact at least, it's very resistable.
This could explain the reports of Dynamic Implosion being resisted by RUNs. As Implosion is a damage dealing attack with additional effect: Terror.
Any thoughts on other direct/add.effect Terror moves that wouldn't be horrible to test?
