There are a lot of misconceptions & misinformation on Relink at this time. This includes other sigils such as Combo Booster. As well as Curio not resetting with quests. Combo Booster only increases your damage on combos and not any consecutive attacks. Curios drops can be reset by doing a quest. However, once a Curio is obtained, you cannot change what is inside. You can test this by backing up your save file. Get a curio drop and see the item. Then replace the save file and get another curio. The items will be different.
so my man you are big legend what is the best build for now for narmaya im following you with the builds but i see you have different sigils now what should i use ?
There isnt really a best build. It depends what suits your playstyle. The max damage sigils on every character is like 1 Crit rate (with Overmastery 20% crit and 10% writhstone crit), 1 Character awakening sigil (or 2 separate with damage cap on it), 4 damage cap V+ (2 if chr sigils with damage caps), 3 Supp V or V +, 1 Tyranny/Combo Booster, War Elemental. Termimus Weapon maxed out.
