There's big jumps in power with 2 attacks, level 3 spells coming online and ability scores hitting 20 with a feat or two in the tank.Can you explain what this means?
For example a fighter can have 20 Dex, sharpshooter and crossbow expert.
Ranger 20 Dex plus sharpshooter
Fighter 20 strength great weapon master plus polearm Master
Spellcasters can drop a level 3 or 4 spells almost every combat. 2 spellcasters means two concentration spells a combat. 20 caster stat plus warcaster.
