Iron Golem prebuffing question

So I have a fast question for necro-specialists.

I know that summoned creatures use the skill level from the moment of casting and take the skill level (aside from the number of summoned creatures).

What about stuff like summon resistance skill? Or Golem Mastery? If I get skill shrine, change my gear to summon-centric (skillers, weapon) will they keep influencing the summon in their elevated state after I change the equipment for psn again? And if yes then will it carry to the next game for the Iron Golem?

Not necessarily a deal breaker, just wanna know if I will be doing the ritual unnecessarily.

Summonables retain the level they were summoned or at when the game is created. So for a skelly army you get your summon kit on, grab a skill shrine and summon up.

For an IG it will take the level you are at when summoned or at game creation when moving between games. Thus if you want to ‘game’ the system on that, end your game in your summoning kit so when you load into the new game it will be the highest level.

After a certain level of + to skills it really doesn’t matter…I usually don’t bother anymore after +10 to summons. Things are pretty sturdy at that point, but everyone get’s their own level for that.

Alright, thanks for the prompt answer. It does seem a bit too much of a hassle to do it then.
