When it comes to Dungeons & Dragons, there are two classes that really let players feel their growth in power more than any others. Of course, getting stronger as the player levels up is a key part of most RPGs, tabletop or otherwise. However, there are some circumstances where a player can start out fairly weak, but by the endgame, they become an absolute powerhouse. A player's build will always affect their character's level of power and versatility, but generally speaking, two classes in Dungeons & Dragons enjoy some of the game's biggest power spikes through the levels.
