This is not a true GRIM.exe guide but rather an analysis on what is the best combination of Attack Speed (AS) and Energy Damage (DMG) Cards to achieve maximum DPS (damage per second) after Paragon patch 29 was released. It should have been pretty straightforward since we have formulas shared with the community. However it was found (by the community) that current AS formula does not align with what we see in the game (refer to this issue report on official dev forum of Paragon.).

In-game measurements

So here is the current state of GRIM's AS on level 15. I'll not focus on how the measurements were captured but they are pretty accurate. I might be doing a separate post on the measurement process but for now let's see the results.

Note that sometimes adding one extra Card Point (CP) to AS will not bring you any benefit (see 5 and 6 CPs). This is probably going to be fixed but meanwhile this is how it is in the game.

Based on this data we can calculate the best combination of AS and DMG cards.

Attack Speed vs. Damage for GRIM.exe

Assuming level 15 with 63 base damage. DMG cards scaling is 1. Assuming as well that we have from 20 to 62 CP to spend on AS and DMG. On level 15 you should already have more than 20 CP and you won't be able to have more than 62 CP... normally. Since you might be willing to have at least a ward (1 CP), some penetration (2 CP) and something else like HP or Lifesteal. I'm not talking about an all-in with 6xWhirling Wand deck.

The results are... interesting.

I was not expecting to see such a few viable AS options in order to achieve maximum DPS. I have checked my calculations and haven't found any mistake. You can check out raw data here. Please let me know if you find any calculation error.

What this means is that to achieve maximum DPS output (assuming you never release a trigger and never miss) you need to plan your deck to have precisely 1,2,5,9,12,14 or 20 CP to AS. Having other amount of CP invested to AS will mean your DPS won't be optimal.

Looking for your comments.
