TMlag

A player can change their TMlag at any time by going in their analytics Options menu and tapping on the green text next to "TM Lags ER". TMlag is a mechanic that will force TM (Tempered Magic) to stop appearing in the Academy until ER (Expedient Recitation) is X levels above TM, with X being the value of TMlag. In short, a higher TMlag value will result in faster casting speed, but a lower overall damage.

Strategy
The damage bonus from TM provides a greater overall DPS increase than the cooldown bonus from ER. This means that with each level of TMlag the players DPS will drop. One may think that increasing your TMlag is a bad thing, because it results in less damage, but many spells mechanically benefit from having a faster cooldown. * assumes the player has not researched Elemental Purity or is using more than one spell of that spell school in their loadout

High TM lag tips
Due to the increase in armour and health of enemies, the decrease of damage due to a high TM lag will slow progress. In general, a low TM lag is better. As you progress, TM lag will need to be decreased for higher DPS. Also the passive increased cast rate from levelling your spells will provide a psuedo higher TM lag. Keep slot 1 for spell exp and the other slots for progression purposes. Some spells to use in loadout to somewhat offset low damage are (list is incomplete and in no particular order):
 * Inferno - bypasses armour
 * Icy Prism - bypasses armour
 * Spark - reduces CD of spell to the left (can end up using a lower TM lag)
 * Ember - offsets enemy's heal with burn
 * ​​​​​​​V Orb - Augs (rank 3 and 5) bypass armour and shock status
 * Ice Wall - freeze status to boost Inferno damage
 * Frost ray - high spike damage
 * Static leap - escapes melee range, shock status
 * Shock net - multi target, shock status
 * Plasma Vortex - Augs (rank 1) reduces armour
 * Flurry - Augs (rank 1) reduces armour and freezes
 * Torrent - freezes, Augs bypass armour
 * F Orb - Augs (rank 3) negates shield and aura, Augs (rank 2) deflects projectiles
