What Loyal actually does
One number defines Loyal: protectiveness +0.4. No courage rider, no discipline adjustment, no threat change. The combat AI simply weights “cover, guard or aid a party-mate” much more heavily whenever it scores the hero’s options for the round. Protectiveness is the parameter that decides how often a hero spends their turn on someone else’s problem instead of their own agenda, and +0.4 is a serious thumb on that scale: only Field Medic (+0.42) sits above it, and the drop to the next tier is steep: Born Mentor at +0.25, Inspiring at +0.18.
There is one other trait at exactly this value, and this is the part worth being blunt about: Team Player is also protectiveness +0.4, and nothing else. The datamine shows no second coefficient on either trait, no hidden rider, no difference of any kind that the fight engine can see. Inside a dungeon, a Loyal hero and a Team Player hero with the same attributes are the same hero. Whatever separates the two names lives outside the combat AI. More on that under recruiting, because it changes how you should buy.
How Loyal reads in the delve report
Protectiveness shows up in the report as a pattern of interventions. The Loyal hero is the one stepping between a wounded ally and the enemy pressing them, holding position beside whoever is bleeding rather than rotating toward a kill, and picking aid options in rounds where a neutral hero would attack. Across a full delve you’ll see fewer entries that end with a party-mate taking an unanswered hit.
That is real value in a permadeath game. Heroes die in the gap between “took a bad round” and “someone reached them”, and +0.4 protectiveness exists precisely to close that gap. On floors with ambient punishment (curses ticking every round, flooded halls sapping the back line), a guardian who stops the one extra hit that would have snowballed is quietly winning the delve.
The cost is action economy. You field four heroes; every guard action is a quarter of your round spent not attacking. A Loyal hero in a fight your party is already winning will still sometimes choose to cover a stable ally, and that wasted round is exactly the kind of slack that clock-style conditions punish. If your reports show clean, fast wins turning into slow, grinding ones after a Loyal signing, the trait is doing what it says on the tin, at a moment when you didn’t need it to.
Party fit and synergies
Anchors and healers wear Loyal best, because guarding is already their job; the coefficient aligns the AI with the role instead of fighting it. A Loyal anchor is the classic bodyguard piece: it lets you run a selfish finisher (a Glory Hunter, a Vain duellist) in the same four, with the anchor’s +0.4 soaking up the mess their negative protectiveness leaves behind. That guardian-plus-hunter pairing is one of the most reliable shapes in the game.
Where it disappoints is on your primary damage dealer, whose rounds are worth too much to spend on escort duty, and in doubles: two heroes at +0.4 in the same party tend to guard each other while nobody closes out the fight. One dedicated guardian per four is the sensible ceiling. If you’re choosing between a second Loyal hero and a Team Player, you’re choosing between the same trait twice.
Recruiting, oaths and when to pass
Because Loyal and Team Player are interchangeable in combat, treat them as a single pool at the market and buy whichever listing is cheaper that week. Sellers don’t price them identically. The names carry different flavour, and flavour moves asking prices, so there is genuine arbitrage in knowing they’re twins. The full case for treating trait twins as one market is in the recruitment guide.
Loyal also has a verified renewal effect: an ask multiplier of 0.88 and +15 percentage points to haggle odds. Oathbound takes precedence if present; Greedy is checked after Loyal. These renewal terms are separate from the ordinary wage modifier. Use the Oath calculator with the matching trait selected.
Ageing is kind to the trait. Attribute value decays as a hero declines; behaviour coefficients don’t. A veteran Loyal anchor keeps intercepting into their final seasons, which makes older Loyal heroes one of the better cheap-experience buys around.
Version history
Nothing has moved. The +0.4 protectiveness coefficient is identical in every build this wiki tracks, v1.9.6 through v2.1.8, and the Team Player twin has stayed in lockstep the whole way. You can plan a roster around Loyal without watching the patch notes for it. Few traits are this settled.
