Over the last few days I've realized that level 30 is a lot more dangerous than I originally gave it credit for, primarily because of the removal of the secondary equipment. There are a few ways to fix this problem, first with precise movement you can pick up 3 Gems on level 22 which should give you enough gold for 2 revives throughout the last few levels, ( ideally used during castle, levels 29, 30), and / or you can add an armor back into the run, both of these options give you a bit more sustainability during castle, at a cost of some time. Ideally these things aren't needed, because it is faster without them, however it is much better to use these strats then to risk dying. Personally I will be trying out both strats, however unless the time gained from more consistently pushing wizard on 30 makes up for the time loss of picking up and equipping the armor, then I will stick to picking up the gems on level 22
