Tricks for Runners to Use
1) Towering
This may seem simple and obvious, but if you are on low health or need to smelt or craft, this could be a game saver. Being this high in the air gives you an advantage over the hunter, as in order to reach you they have to either tower or have an ender pearl. However, if they have a bow they could knock you off at long range, so I would suggest placing blocks behind you as a sort of makeshift railing. This could also be uses to knock hunters off the tower and have them take fall damage. For example, in Dream's recent survivalist vs. 3 hitmen video, he lures Sapnap and GeorgeNotFound onto a bridge made of leaves, and using his shears took the blocks out from under them and thus threw them down onto the ground many blocks below. In another video, Dream uses a fishing rod to pull his friends off their towers as well. Overall towering is an easy-to-implement plan that gives you an advantage. The only downside is that this strategy is basically a beacon to the hunters, and may not be the best plan for a more sneaky runner who wants to avoid PvP at all costs. Also, unless you can kill the hunters, you are going to have to get past them eventually. Personally, I would recommend practicing your MLG skills before using towers.
