Larian Studios Forums Baldur's Gate III Baldur's Gate III - Technical & Gameplay Problems Gather Allies question

I reached the end of High Hall (brain stem) forgeting to summon any allies
As I am on the hardest setting I cannot reload and check how that Class Action works, so I'll ask - can I summon ALL of them at the same time, or only ONE bunch?
I.e. if I summon X I cannot summon any other group?

BTW - I understand the one use only things
BTW2 - High Hall is easy, even if near its end the orbital bombardment by the Tyranid Hivefleet nautiloid is irritating. At times I found it difficult to discerne where exactly the Nautiloid was aiming, due to the flaming surfaces. Must be a horror for colour blind people ...
BTW3 - I found three hawt! Short Race female teenies hiding in a side room. What is their purpose? For the edgelords paying Durge to murder them? Funny - I blasted the door to bits and THEN I started the Three Little Pigs "open the door, please, I so not evul! I pinky swear so am not!" dialogue with them.

Every party member can summon an ally (party or effect) as an action each turn. Given enough turns you can invoke them all on the same battlefield. But they can appear only within a certain distance of the summoner, so if you want them to appear in a certain spiot, the summoner must be max. 18 m (I think , it could be less) away from there. For instance, if you summon Isobel's healing, it can't be applied to a party member at the other side of the battlefield.
