This includes: enemy dodging that would not normally be an issue and is unintuitive, such as enemies that deal a small amount of damage and awkward dodging while artificially morphed;
bypassing door locks while in G-mode to maintain indirect G-mode in the next room;
exiting G-mode while inside of overloaded blocks in order to have them solidify and be able to X-Ray climb.
Getting a usable amount of Energy for G-mode setups where there is a high risk of taking extra damage beforehand can often benefit from getting close to the correct position,
taking an enemy hit and then using X-ray and waiting for Samus's i-frames to expire in order to be able to take additional hits without the enemy moving very much.
