I’m not a namor expert but I’ll tell you what I know. Namor’s sig scales so that once you’re at max sig he doesn’t take any damage while attacking and does that damage back to the opponent. This includes nodes like thorns or champion abilities like electro and Korg. At lower sig he still reflects some of the damage but a portion of it is done to himself. His biggest and most important ability is imperious Rex. When namor reaches 30 imperious Rex charges he gains his full power, his specials are unblockable, and when he uses a special his power bar replenished a certain amount. I’m pretty sure he gets a damage bonus during this time also. The rotation that you normally want to go for to maximize this period is throw a special 3 right before imperious Rex so you can get a fury from it and then throw one right after it has trigger. This means you get 2 furies from his sp3 and then can throw as many sp2s and 1s as you can get in during imperious Rex. I don’t have a ranked up namor, I have a 5* who is at sig 20 and I don’t want to rank him up till he gets to higher sig levels, so I’m not a master at his rotation and that’s pretty much all the information I know. To anyone else commenting on this thread, if I said something wrong please correct it.
