Diablo 3 Monk Survivability Model v1.0.4


Since releasing the Monk Survivability Model on the Diablo 3 forums, I’ve gotten a number of questions about optimal use of the calculator. What follows is a set of instructions, along with answers to a few questions about how the model works.

What is Time-to-Live, anyway? – If it helps, you can think of Time-to-Live as Effective Health.. per Second. By combining your character sheet parameters with an attack speed and damage estimate for a particular boss, champion pack, affix, etc., you can evaluate the value of various stats and skills as a function of how much longer they allow the Monk to live under the fight conditions entered.

Why use Time-to-Live?! Effective Health works fine and is easier to use! – Yes, there are a lot of Effective Health calculators out there, and *some* of them have all of the various mechanics correct. The primary reason to use Time-to-Live rather than Effective Health is that the Time-to-Live method is able to directly compare the relative value of all stats (not just mitigation and Life pool stats), including attack speed modifiers and debuffs, various forms of life regeneration, skills with cooldowns, etc. Yes, it does take more work, as time-to-live requires estimating the pre-mitigation attack speed and damage for a particular fight of interest, and of course it means that the output is subjective too, and based in part on the fight parameters entered. For example, it is quite possible to enter a damage and/or attack speed low enough that the calculator will report your time-to-live as infinite.

How to use the Calculator:

  1. Dismiss your follower (right-click on their portrait at the top left of the screen). The Enchantress and Templar both can provide bonuses that affect your character sheet values. The model will apply these bonuses for you if you check the box for them, but if you have a follower hired when you input your character sheet values, the result will be overvalued in the model.
  2. Cancel your Mantra, if active (right-click on its icon at the bottom of the window), and any other temporary buff you may have active (e.g. the Blazing Wrath Rune buff). Again, the model will apply these bonuses for you if you check the boxes for them.
  3. In your Passive Skills section, if you are using ‘Seize the Initiative’, ‘One with Everything’, or ‘Chant of Resonance’, switch them with any other Passive Skill. Just like in the case of #1 above, if you have any of these skills active your character sheet will reflect the higher value already, and the model will double-count these bonuses if you check the box for them.
  4. Simply transfer each character sheet (and details screen) value into the matching calculator field. (Updated for v1.0.5) There are a few fields where you need to look at your individual items to get the correct value to enter. For main-hand and off-hand attack speed, enter the attack speed found on each of your weapons (leave the off-hand attack speed as zero if you are not dual-wielding). For the increased attack speed % field, add up all your attack speed modifiers on items (except weapons), and enter this total in the field. For Life per Spirit Spent, add up all of your Life per Spirit Spent from gear only (i.e. don’t include the 62 from the Passive Skill Transcendence, as the model will include this automatically if you check the box for it).
  5. Configure the ‘Enemy Settings’ section as desired, using an estimated attack speed and pre-mitigation damage for the fight of interest. Here are some example parameters you might use, for each act of Inferno: Butcher in act 1 hits for roughly 120000 damage every 0.5 Seconds; the Rock Giant champions in act 2 hit for roughly 200000 damage per second (it’s actually two quick punches followed by a pause), or up to 3 attacks per second for all three of them attacking you at once. The hardest-hitting champions in acts 3-4 hit for upwards of 300000 damage per second. Plague ticks for roughly 45000 damage four times a second, with other affixes ticking for a bit more than that.

How to use the Item Comparison Tool – There are two methods for using this feature to compare items, one for comparing two items you aren’t wearing, and one for comparing the item you are wearing to another item.

  1. If you aren’t wearing either of the items you want to compare: for best accuracy, you also want to remove any item you are wearing in that slot, and use those character sheet values. Then simply enter the item stats for the two items in the appropriate fields (it doesn’t matter which item goes on which side).
  2. If you are wearing one of the two items you want to compare, put the stats of that item in the item 1 side, and check the checkbox for ‘item is being worn’. Put the stats for the item you aren’t wearing (and want to know the value of) on the item 2 side.

Changes with v1.0.4 – The current version of the model includes the following changes:

Added a checkbox to simulate using all excess Spirit on the 3sec Mantra buff – works for both Mantra of Evasion and Mantra of Healing.
Added a checkbox to the item comparison tool to indicate ‘item is being worn’. – usage mentioned above.
Added mouseover tooltips for most skills. – as per a suggestion for cleaning up the interface.
Adjusted the build-in attack speed modifiers on primary attacks slightly. – as per better data on the built-in attack speed modifiers here.
