Opening up your character sheet and hitting K takes you right to those reaction settings which are pretty crucial for managing your whole party's combat abilities. The real trick is switching important reactions from on to ask mode especially for things like divine smite and cutting words since you dont want your companions burning through resources automatically. When you set things to ask youll get a popup whenever the reaction could trigger, giving you way better control over when to use those powerful abilities

The timing on these is actually super important since reactions like divine smite can make or break a tough fight. Your companions might have the perfect reaction ready but if its set to auto-fire, they could waste it on a basic enemy instead of saving it for when you really need it. Maybe interesting - setting reactions to ask for your main damage dealers first since theyre usually the ones with the most critical timing-based abilities

Just remember that even with optimal reaction settings, youll still need to manually control your companions basic actions in combat. The reactions are just about those specific triggered abilities, but getting them right makes a huge difference in how efficiently your party handles tough encounters especially when resources are running low
