Lately I have been contemplating the big boys of Underrail, Industrial bots, Dreadnaughts and Naga Protectors being inmune to any sort of inmobilization, which makes sense due their size, weight and strenght. It makes sense.
I also saw how Fatso becomes inmune to entanglement the angrier he gets, due Adrenaline Rush pumping his STR to 20. Which also makes sense.
My idea is, what if the player character can become inmune to inmobilization so long s/he has 20 STR, be under the effects of drugs, gear or food. You lose inmobilization inmunity the moment your STR drops to 19 and below. This prospect is not entirely now, since having high STR will cut throwing net entanglement from 2 to 1, which makes sense.
And not to mention, there's nothing more anti-climatic than charging at Big T like a furious Bison under all drugs know by mankind, just to get completely shut down by acid entanglement.
