Without getting fall control, there's no way back from Sen's Fortress if you skip the gate with Sen's skip so you can't take any bonfires. With this you can, and you don't need to waste levels to use fall control. We memeroll in this game. You can kill Iron Golem ( with Tarkus if you need to) and get to Anor Londo early to go grab some goodies, and return to early game. Note that picking up certain weapons like the lightning spear will put you at +10 weapon so you can only match with +5 or higher. But, if you don't care and wanna be OP early, this will help ;)
