AFK Journey Invite Letters, Diamonds & Recruitment Guide

Invite Letters fund All-Hero Recruitment, the broad standard recruitment pool. Diamonds are also accepted there. Its Wish List lets you narrow eligible hero outcomes by faction rather than pick a guaranteed hero for each attempt.[1][2]

Epic Invite Letters fund Epic Recruitment, which uses a five-hero choice list. Prydwen documents this as a letter-only banner: ordinary Invite Letters and direct Diamond spending are not its payment options. The community Epic Recruitment reference corroborates the dedicated letter type and choice list.[1][3]

Rate Up Recruitment accepts its matching Invite Letters or Diamonds. Stargaze is another recruitment option: the community Stellar Crystal item description assigns that item to the Stargaze Station. Buying a recruitment resource elsewhere and using it on its matching banner are separate steps.[1][7]

The community All-Hero reference documents one Invite Letter per attempt, or 300 Diamonds for a single recruitment and 2,700 for ten together. A ten-letter bundle therefore funds ten attempts; it does not promise ten heroes, since recruitment can also yield Acorns.[2]

Prydwen documents no equivalent ten-pull Diamond discount for Rate Up Recruitment. A Diamond balance therefore has a different purchasing power depending on which recruitment you choose.[1]

The community Gold reference lists character levels, equipment and artifact upgrades as uses. In Starter Story leveling, Gold works alongside Training Manuals and Hero Essence; AFK Global’s planner separately accounts for these resources. Receiving Gold alone therefore does not necessarily remove a leveling bottleneck.[4][5]

Ascension raises a hero’s tier and uses duplicates and, where applicable, Acorns. Prydwen distinguishes faction-specific Acorns from universal Omni-Acorns. Celestial and Hypogean ascension uses duplicates without Acorns. AFK Global expresses duplicate requirements as Soul Sigils.[5][6]

This makes resource quantity context important: a pile of faction Acorns cannot replace a missing hero duplicate, while a letter is an attempt to obtain recruitment rewards rather than an already-owned duplicate.[2][6]
