[Infinitode 2 1.9] DQ1 Score 2.08m: Thunder Strikes on Level Up is Surprisingly Good

Hello guys!
The bonus of thunder strikes on tower leveling up above 10 can often be underestimated.
The damage of triggered thunder ability is based on your global MDPS instead of towers' local MDPS. It can be triggered once on each exp level & each tile.
An important strategy shown in this video is to manage this thunder, letting them work when you need them.
Another thing is about the core in bonus. We know the bonus sequences can have 3 stages: 1-5, 6-10, 11+. The power of some specific bonus can be different based on this. For bonus of adding a core, it results in a purple core in the first 5 bonuses, orange core in 6th to 10th bonuses, and cyan core on 11+. Thats why you can not get a cyan core from bonus in DQ maps.
Moreover, once you select a bonus, the possibility of the same bonus to appear will be multiplied by a parameter. For adding a core, this parameter could be 0.1 and thats why it is so hard to find double core sequences. Also, there can be at most 2 cores on these DQ maps so you dont need to try to find double core sequence if the map itself has a core.
