When i first come to http://wiki.spiralknights.com/Damage#Monster_Resistances , it was difficult to me to understand and memorize, which type of damage is good versus which type of monsters. Damage table was too disordered for newbes, like me in past. So i make a simple scheme, on which every newbe can understand, what monsters weak against what damage, and what monsters strong. Weakness is background color, and defense is the monster types on the opposite side.
I'm bad in drawing, so if someone can make this scheme prettyer and post it in wiki, i will be glad.

P.S. And sorry fo my terrible english >_<
When it comes to learning strategies there are many ways to memorize the table.
For example, I am a logic/mathematic learner, and since I was primarily bombing when I was getting more into the game I attributed weaknesses and resistances to what weapons I was using: mostly Barrage and Graviton. Barrage charges and attacks faster than Graviton in a larger radius, meaning it would nail mobile enemies like beasts and fiends. Graviton pulled enemies into it then blasted them around, meaning it worked well against crowds of jellies or gremlins derping along. Since my first element bomb was Voltaic line, but at the time Roarmulus did not exist yet, I just used my Barrage and Graviton lines for everything. Crowd of robots? Graviton. Crowd of undead? Barrage. Usually I ended up using both together for almost everything, first Graviton to bring them together then Barrage to hit while they spin, but if most of the crowd is pierce resistant I would chain Graviton to make them spin until death.
I learned based on what I used in practice and scenario, not by staring at the table as a visual learner would or repeating the table out loud as a auditory learner would. From what I have heard logic/mathematic learning is supposed to be the most difficult method but has stronger results, though the process can be longer and more difficult. Delayed gratification.
That table would be great for visual learners, maybe pattern people as well. Because colors. Yurp.
