Crit:

• Tenacious Bond allows for your Warframe to gain a 1.2x Crit Damage buff with the use of Bite.

Efficiency:

• If you're going to replace a mod for something else this is the mod I would choose, unless you don't care about survivability.

• Seismic Bond allows for your Warframe to gain up to 30% extra ability efficiency with each bit of damage done.

Utility:

• Synth Fiber no longer is needed to assist with mods like Equilibrium since it can pick up orbs at max health by itself.

• The essential utility mods such as [Charm], Primed Animal Instinct, and Fetch help with looting and Tek Enhance improves the duration of Charm buffs.

Survivability:

• If the Warframe you're using is using a mod that increases shields or armor, [Link Redirection] or [Link Fiber] will most likely be the better choice over Calculated Redirection or Metal Fiber due to changes made to them in the newest update.

• Metal Fiber/Link Fiber and Enhanced Vitality/[Link Vitality] helps the Kavat reduce the amount of damage taken. Shields have a longer invulnerability timer the more shields the Kavat has now, but after doing some testing with the shield mods (Calculated Redirection / Link Redirection and Hastened Deflection) I've found that the Metal Fiber/Link Fiber and Enhanced Vitality/Link Vitality combo still works better for overall survivability. Medi-Pet Kit also will help lesson the affects even more.

• If the Kavat does die you have the -3s and -15s recovery time from Tenacious Bond and [Medi-Pet Kit] to reduce the time needed.
