Might as well chime in here - Don't ignore defiler+ actions when trying for an orgy. They deal a lot more damage than the base defiler actions, and they deal it to an additional circumstantial damage type.
I'm going to delve a bit into the underlying mechanics here, there's some interesting multipliers to keep in mind that aren't in the guide. We'll call the amount of damage done by your basic actions the "baseline" surround damage. All actions have a basic damage "profile" - they deal max damage to their designated trauma, 1/2 to secondary, 1/4 to tertiary, and 1/8 to the final trauma (80-40-20-10). The same setup is applied to circumstantial damage. (100-50-25).
Basic actions compound damage, but that damage is also reduced by the chosen's tactics. x0.6 with one applicable, x0.4 with both.
Defiler and Defiler+ actions deal 2x baseline damage. They are unaffected by the chosen's tactics. Additionally, Both Defiler and Defiler+ actions receive a 2x damage bonus if the target chosen has a T2 break in the secondary circumstantial damage type, and is currently at Lv3+ in that circumstance type. Defiler+ actions receive an additional x2 bonus damage for fulfilling the same requirements on their tertiary damage type. Finally, Defiler+, being a group surround action, receives a scaling damage modifier based on the target chosen's relationship. (x1.2 -> x2 | the worse the relationship, the higher the multiplier | There's an item that lock this to 2x, regardless of relationship).
Orgies operate on a completely different damage system. First, it deals the same base circumstantial damage of a defiler action to every damage type, including trauma. So it deals more damage to trauma than a standard defiler action. Next, orgies benefit from the same 2x modifier for past T2 breaks, with current circumstantial damage, that defiler actions benefit from. so max x16 damage from that. Additionally, as a group surround action, they receive a further scaling bonus based on their relationships. Same rules as above, applied for both chosen.
A consequence of this is that some distortions are inherently stronger against specific defiler actions. Temptation and Aversion forsaken cannot benefit from the T2 x2 bonus damage of a defiler action. Rampancy can only benefit from the Broadcast bonus, and negotiation can only benefit from Force Orgasm bonus.
