Rod

Uncommon Transmutation

While holding this segmented, 1-foot long rod, you can speak its command word as an action to cause it to extend in either direction. The rod can extend up to 50 feet, up to as far as the surrounding space allows. If the rod touches another creature or surface before reaching its full height, the rod stops moving in that direction. If it stops moving against a solid, unmoving surface, the rod fills the gaps to hold firm against it. The rod is unwieldy to hold once it's longer than 10 feet, forcing you to make a Strength (Athletics) check to maintain your grip on the rod while it's extended beyond that range. The DC for this check is equal to 8 + 1 for every 5 feet beyond 10 that the rod is extended. For example, the DC is 9 while the rod is 15 feet long, but 16 while full 50 feet. If you lose your grip and drop the rod or use it to make an attack while it's extended more than 10 feet, it immediately retracts back to its shortened length. You can speak the rod's command word again as an action to cause it to retract.

Aiming the rod carefully, he spoke a single word and watched as the form began to change. With a series of frantic clicks and clacks, the rod's segments multiplied and grew, extending the length of the pole . When it reached the far side of the chasm, he inspected the rod's hold on the rocky ledges for its security before beginning the slow, perilous climb to the other side.
