Summon Mastery

Summon Mastery 0.1.2

Summoned creatures grow stronger with the upgrade rank of the weapon that creates them. Nearby following summons can accompany you through portals without being replaced or healed.

Initial development release for Valheim 1.0.7. Build, offline rules/API checks and plugin initialization in Valheim have been verified. Combat balance, portal travel and multiplayer still need gameplay validation. See the verification report.

Dismiss summons

Press O during gameplay to dismiss all of your living summons tracked by this mod in the current world, including waiting, hostile and unloaded summons. Other players' summons, ordinary pets and wild creatures are left alone. Dismissal grants no drops or skill rewards. It cannot be undone; summon new creatures if you want them back.

Change Controls / Dismiss all summons in a BepInEx configuration manager, or edit BepInEx/config/local.summonmastery.cfg while the game is closed:

[Controls]
Dismiss all summons = O

Modifier shortcuts such as O + LeftControl are supported; None disables the shortcut. The key is ignored while typing, in menus/inventory/map, during death/cutscenes or portal travel. All clients and the server need version 0.1.1 for the new dismissal request.

Spirit Caller: wolves only

Enable Summoning / Spirit Caller wolves only to make new Spirit Caller casts summon only ghost wolves instead of randomly choosing bears, moose, wolves or boars. It is off by default. Use a BepInEx configuration manager, or edit the config while the game is closed:

[Summoning]
Spirit Caller wolves only = true

Existing spirits remain unchanged. Normal casting costs, summon limits, Blood Magic, weapon-rank scaling, portal following and dismissal continue through the normal paths. Other weapons and wild wolves are unaffected. If another mod or a game update removes the ghost wolf from the cast's selection pool, the mod logs a warning and keeps normal selection for that cast. The option is captured at cast start; changes affect the next cast.

The selection mechanism has been verified against the installed game's assets and tested with coroutine fixtures. Live wolves-only casting has not yet been tested. Use 0.1.2 on all peers; this setting is per casting client, like the existing scaling settings.

Scaling

Scaling / Exclude Trollstav is off by default. Enable it to leave newly summoned Trollstav creatures at their normal health, regeneration, armor, movement and damage:

[Scaling]
Exclude Trollstav = true

Normal game and Blood Magic effects remain. Excluded trolls are still tracked for the dismiss shortcut; their hostility and portal eligibility are unchanged. Existing summons keep the stats recorded when they were cast, so dismiss and summon again after changing this setting. Spirit Caller and Dead Raiser scaling are unaffected.

Rank means the weapon's upgrade quality, not Blood Magic level or creature stars. Bonuses interpolate from unchanged stats at rank 1 to these configurable maximums:

| Stat | Maximum-rank bonus | | --- | --- | | Maximum health | 3 times normal summon health | | Regeneration | 0.5% of maximum health per second, after 10 seconds without damage | | Added armor | 35, using the installed game's normal armor formula | | Movement | 30% faster walking, jogging, running, swimming and flying | | Damage | 2.5 times normal attack damage |

For a weapon with four upgrade ranks:

| Rank | Health | Added armor | Movement | Damage | Regeneration per second | | --- | --- | --- | --- | --- | --- | | 1 | 1x | 0 | 1x | 1x | 0% | | 2 | 1.667x | 11.67 | 1.10x | 1.5x | 0.167% | | 3 | 2.333x | 23.33 | 1.20x | 2x | 0.333% | | 4 | 3x | 35 | 1.30x | 2.5x | 0.5% |

The intention is strong same-biome support at maximum rank, especially Dead Raiser skeletons in the Mistlands. These are initial tuning defaults, not a verified balance claim. Existing Blood Magic, star, resistance and world-difficulty effects remain in place. Armor still allows damage: an isolated 100-damage slash hit becomes 65 after the added 35 armor, before considering other effects. Damage restarts the healing delay. No immunity, resurrection, attack-speed increase, or unlimited summon count is added.

Each creature records the casting weapon's rank and bonuses when summoned. Changing weapons or upgrading the staff afterward does not change existing summons. Configuration changes apply to newly summoned creatures. Recorded bonuses survive normal world reloads and network ownership changes without multiplying repeatedly.

Creature coverage

• Dead Raiser melee skeletons and archers use the game's SpawnAbility path covered here.
• The same hook covers other weapon-created creatures using SpawnAbility, including

Trollstav's summoned troll when the weapon is passed through the normal projectile chain.

• Original factions and hostility are preserved: a hostile summoned troll becomes stronger

unless Exclude Trollstav is enabled, and is not converted into a friendly portal companion.

• Direct attacks, attack-generated projectiles/areas and independent owned area effects

are covered. Attack-generated areas are not multiplied twice.

• Wild creatures, ordinary pets, enemy summons, and spawned effects without a creature

are excluded. Third-party summoning implementations that bypass SpawnAbility or omit the casting weapon need an explicit integration; universal mod compatibility is not claimed.

• Existing summons from before installing the mod cannot reveal which weapon rank created

them. Summon them once with this mod loaded to enable tracking and portal support.

Portal travel
