I hope you enjoy the arcanaruna, and I'll see you tomorrow with a pretty fun froggy monster!
This looks delicious!
Multiple glyphs of varying shapes cover this gray frog’s skin. Several of them glow with a torch-like intensity.

Absorb Magic (Su) When a spell or spell-like ability fails to overcome an arcanaruna’s spell resistance, it is absorbed by the arcanaruna. If the spell or spell-like ability affected an area, it completely fails to function, but a spell or spell-like ability with multiple targets work on the other targets. The arcanaruna heals a number of hit points equal to twice the spell’s level. Additionally, the arcanaruna can choose one of the following options: increase its deflection bonus to Armor Class by a value equal to 1/4 the spell level (minimum 1), add the spell to its spells known, or add the spell level to a spell point pool (for its arcane formation ability). The deflection bonus and the spell point pool last for 1 hour, while the additional spells known last for 24 hours.
Adaptable Energy Resistance (Su) As a free action at the beginning of its turn, an arcanaruna can lower one energy resistance by 10 to increase another energy resistance by 10 or give itself immunity to the chosen energy type if the energy resistance is at 30. Alternatively, it can reduce an immunity to an energy type to resist 30, so it can increase another energy resistance by 10 (or change it into an immunity as above).
Arcane Formation (Su) As a standard action, an arcanaruna can use its spell point pool to create an ioun stone or create a sigil that acts as a symbol or glyph spell. It must expend spell points equal to the price of the ioun stone divided by 1,000, or the level of the spell. Stones created by the arcanaruna only last for 1 hour if the it remains alive. However, if the arcanaruna is killed, any stones it created become permanent. Sigils have a duration per the spells they duplicate.
Magic Siphon (Su) If an arcanaruna succeeds on a touch attack with its tongue against a target, it can choose an item in the target’s possession to suppress its magic for 1d4 rounds. The arcanaruna must be aware of the item (typically through the use of arcane sight) to choose an item. The target must succeed on a DC 23 Will save to avoid this effect. If the target fails, the arcanaruna increases its spell point pool by a value equal to 1/2 the item’s caster level. The save DC is Wisdom-based.
This gray frog is no larger than a cat. It has a dimly-glowing rune on each flank. The gleam of intellect in its eyes betrays its seemingly animal nature.

Adaptable Energy Resistance (Su) As a free action at the beginning of its turn, a juvenile arcanaruna can lower one energy resistance by 5 to increase another energy resistance by 5. It cannot have an energy resistance better than 10 using this ability.
Magic Suppression (Su) If a juvenile arcanaruna succeeds on a touch attack with its tongue against a target, it can choose an item in the target’s possession to suppress its magic for 1 rounds. The arcanaruna must be aware of the item (typically through the use of detect magic and concentration for 3 rounds) to choose an item. The target must succeed on a DC 12 Will save to avoid this effect. The save DC is Wisdom-based.
Arcanarunas come from a now-dead world somewhere in the dark corner of the universe. Given their predilection for absorbing magic wherever they travel, it is likely this odd species with a similar appearance to frogs caused the catastrophe that destroyed their world. Those who have managed to study the creatures and keep their magic intact trace their path through the Material Plane and other dimensions to other dead or dying worlds.
Arcanarunas claim their sole motivation is to catalogue all the world’s arcane magic. If they have to rip it from selfish beings who hoard their knowledge and power to themselves, so be it. They usually attempt a more benign approach when encountering an arcane caster, presenting themselves as students and practitioners of the art. If that doesn’t work, they goad spellcasters into casting spells on them, so they can absorb and study the spells. If arcanarunas join a fray with a mixture of arcane spellcasters and non-spellcasters, they target the non-arcane spellcasters for destruction while leaving the spellcasters intact. After all, they don’t want to destroy their meal tickets.
Arcanarunas live for 800 years. They produce offspring at a slow rate, and often send the innocuous-looking spawn to hunt for arcane spellcasters to whom they can attach themselves as familiars. While the contract between “master” and familiar precludes these juvenile arcanarunas from directly killing the spellcasters they serve, they often arrange for assassinations when they feel they are ready to reach adulthood.
A spellcaster of at least 7th level who has the Improved Familiar feat may select the juvenile arcanaruna as a familiar. The arcanaruna bestows its energy resistances and spell resistance to the spellcaster when they are adjacent to each other.
