Understand Fass Canticle
Useful when…
- Tome setups that provide shield-recharge support to nearby allies
- Squad play where allies remain within Affinity Range
Effect and trigger
Fass Canticle is an exilus Tome mod. Killing enemies grants allies in Affinity Range a shield-recharge bonus for 15 seconds. At rank 0, the bonus is 25% Shield Recharge Rate and −7% Shield Recharge Delay; at rank 2, 35% and −21%; at rank 3, 40% and −28%. The stated trigger is a kill, and the recipients are allies within Affinity Range.
Investment and Tome slot
It has three ranks, Naramon polarity and base drain 4. Example fusion costs are 30 Endo and 1,449 Credits for ranks 0→1, 60 Endo and 2,898 Credits for 1→2, then 120 Endo and 5,796 Credits for 2→3. The final rank raises the stated rate bonus and delay reduction; weigh that gain against the cost. It is incompatible with Jahu, Khra and Lohk Canticle. Those alternatives have distinct listed effects: enemy Armor and Shield reduction, Universal Orb drops, and ally Fire Rate respectively.
Practical limits
The support requires kills to activate and applies to allies in Affinity Range for 15 seconds. Do not assume it affects allies outside that range or gives its shield benefits without a kill trigger.
Limitations and tradeoffs
- Uses the Tome exilus slot for ally shield-recharge support.
- Effect depends on kills and allies being within Affinity Range.
Common mistakes to avoid
- Assuming the buff applies beyond Affinity Range or without a kill.
- Trying to equip it alongside an incompatible Canticle.
