Plando allows you to have total control over item placement.
You can place a specific item on any location and locations not specified will be filled following the normal algorithm.
You can also specify the settings that the algorithm follows after taking your item placement into consideration, what items Link starts with, what items are in the item pool, which dungeons are vanilla or MQ, which trials are active, and where entrances lead to.
How to Plando:
Use the Plandomizer below to create an OoT Randomizer plandomizer file with your preferred settings, locations, hints shenanigans
Most aspects of an OoTR Seed are completely customizable here. Everything not defined will still be randomized by the randomizer.
Please note that the plandomizer is not verifying most of your settings, so it is still possible that the randomizer will reject your file if the settings do not fit with logic.
Hit the Generate Plando File button to get the JSON file.
Use the generated file to create YOUR seed using the OoTR Application or the Web Generator.
