Cyrille is the first expert anyone mentions for Bear Hunt. Here's every skill's numbers and unlock conditions on one page — plus which ones to level first, with community opinions to back it up.

Cyrille
Expert · Bear Hunter (Bear Hunt specialist)
Cyrille is the "Giant Bear Hunter" — a Bear Hunt specialist expert. The official wiki calls him "one of the most legendary hunters of the ice fields," a "beast killer," and (lore-wise) Klaris's mentor. He survived a giant bear attack in his youth and has fought beasts for twenty years since. Fitting résumé for the job.
Lore aside, one thing makes him matter: his talent "Hunter's Heart" adds a flat +30% to your final Bear Hunt damage points. As covered in our damage mechanics guide, nearly every way to raise Bear Hunt points is "raise raw damage" — Cyrille is the rare exception that raises the point-conversion rate instead.

Effects and unlocks per the official wiki. Upgrades consume Books of Knowledge and learning XP (e.g. Entrapment Lv2–10 costs 3,600–32,400 XP).
This talent is the heart of the matter. Per-level values below — it reaches +30% at Lv11.
| Lv | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 |
|---|---|---|---|---|---|---|---|---|---|---|---|
| Bonus | +2% | +4% | +6% | +9% | +12% | +15% | +18% | +21% | +24% | +27% | +30% |
Per-level values are our own research (cross-checked against community sources and in-game text). The official wiki lists only the +30% max.
The key detail: the bonus applies to your final point total — after attack, lethality, exclusive gear, pets and hero skills are all calculated, the result is multiplied by 1.3. If one rally earns you 20 million points, Lv11 makes it 26 million. Over 10 rallies in an event, the gap grows to 60 million points — without changing a single hero or soldier.

For Bear Hunt focused players, the order is:
Cost-wise Cyrille is also the cheapest expert to raise: Altema's comparison puts Agnes at ~1.2×, Bald at ~2×, and Romulus at several times to tens of times Cyrille's cost — hence the common advice that F2P and light spenders should start with Cyrille.
For an outside view: Altema scores Cyrille 9.0/10, citing the +30% point bonus, the capacity boosts, and the fact that even low-power players benefit from the material skills.

The overall consensus: "Cyrille first if you do Bear Hunt" is barely contested — the real debate is how far non-Bear-Hunt players should take him. Next section.
Honestly: it's not mandatory. Hunter's Heart only raises Bear Hunt points and does nothing for PvP damage. If SvS and Foundry are your game, Cyrille Lv11 is "nice, not urgent."
Zero investment isn't quite right either, though. Bear Hunt is a main source of gear materials (Essence Stones, Enhancement Components), and a Cyrille with Weapon Master and Scavenging leveled quietly funds your PvP gear every round. A sensible PvP-first build is "both material skills + Hunter's Heart to a mid level." The early talent levels gain a steady +2–3% each, so just feed him spare XP as it comes.
FAQCyrille owns an irreplaceable talent — +30% Bear Hunt damage points — that makes him effectively required for Bear Hunt players. Order: Hunter's Heart → Weapon Master & Scavenging → Entrapment (leaders) → Ursa's Bane. PvP-first players needn't rush max level, but the material dividends alone justify some investment. Try flipping Cyrille's level in the simulator to see your own numbers move.
