Hello there,

As per Wiki:

• Tenet Detron: Higher critical and status chance; can burst-fire its entire clip.
• The weapon's max rank caps at 40 after 5 polarizations - max rank increases by 2 per Forma added (similarly as the Paracesis).
• All Tenet weapons deal innate elemental damage in addition to physical damage. The amount of this damage is random, ranging from 25-60%, while the type of element is determined by the Progenitor Warframe, as per the table below:

According to the above, I added exactly 5 forma to this weapon, so we can obtain Mastery Points from it.

In this case, I recommend picking Magnetic as an elemental.

Some facts about weapon:

• Alternate Fire shoots all remaining ammunition in the magazine in a quick burst.
• Has linear damage falloff from 100% to 37.5% from 13m to 22m target distance (distances are affected by Projectile Speed).
• Projectiles have travel time.

This is still one of the "weapon of choice" for [Mag].
