RPG - Dragon Repeller

--- id: 5d708be9066dac7142a6d79c title: Part 74 challengeType: 0 isHidden: true --- ## Description

We have to fix an error. The `currentWeapon` variable is the array index. Array indexing starts at zero. The index of the last element in an array is one less than the length of the array. In the `if` condition you are working on, change `weapons.length` to `weapons.length - 1`.

## Instructions
