The Greatbow is a classic weapon that’s a good choice for anyone looking to build power. Of course, the Greatbow isn’t necessarily the easiest weapon to find. There are several enemies wielding this bow, but only select enemies actually drop it. However, you can find a guaranteed large bow on the Altus Plateau. How to get the Greatbow in Elden Ring.
Before you can get your hands on the Greatbow, you must head either east to the Caelid region or north to the Altus Plateau. If you decide to go to the Caelid region, you will look out for Fort Gael. This fort is on the western side of Caelid. The Radahn Knights in this stronghold have a chance to drop the Greatbow. This doesn’t happen often and can be a lot more tedious than going to the Altus Plateau.
If you decide to go to the Altus Plateau, you must first collect the two halves of the Dectus Medallion in Fort Faroth and Fort Haight. This allows you to use the Dectus Grand Lift. If you don’t want to take the elevator, you can always ride through the dungeons that connect Liurnia to the plateau. Once you reach the Altus Plateau, head east along the road, then follow it north. Outside the northern section of the capital wall is the Highway Lookout Tower. Climb to the top of the tower to find a chest containing the Greatbow.
