Runestones are powerful unique items for companions that both enhance the companion’s and your character’s stats.
5 types of runestones exist:
There are 15 levels, which are different from each other and increase stats depending on the level of the runestone. (Level 15 bonding runestone gives 70%, while level 13 gives 60%).
Runestones are an important aspect of the game, since many of them are extremely impactful on your further leveling.
- Mysterious runestone
- Bonding runestone
- Profane runestone
- Arcane runestone
- Empowered runestone
- Recondite runestone
Separately from runestones there are enchantments, which are inserted into the second slot in helmet and gloves.
- Greater Black Dragon Glyph
- Greater Red Dragon Glyph
- Greater Green Dragon Glyph
- Greater White Dragon Glyph
- Greater Blue Dragon Glyph
Also, there are smaller dragon enchantments with the same names, their differences are miserable, so there is no point in going over them, their duration is 1 hour.
There are also enchantments entitled black Ice enchantment that can be received from Kessell’s Retreat or can be made with black ice refinement.
- Greater Corrupt Black Ice Enchantment.
- Greater Corrupt Piercing Enchantment.
- Greater Corrupt Lethal Enchantment.
- Greater Purified Restoration Enchantment.
- Greater Purified Tempered Enchantment.
- Greater Purified Black Ice Enchantment.
They do not cost much, but will make the game much easier for you. Their duration is 8 hours. (Lesser versions of the same enchantments also exists).
There are also frosted glyphs that can be obtained by completing the “Create a frosted glyph” mission from the “Storm King’s Thunder” campaign. From the received pack you will be able to pick one of the four glyphs of your choice, their duration is 2 hours.
- Frosted Lethal Glyph.
- Frosted Smiting Glyph.
- Frosted Tempered Glyph.
- Frosted Protection Glyph.
Also, there are enchantments for strongholds and there are a lot of them, but they are quite useless.
In conclusion I should say that runestones can increase your stats by a ton, that is why it is worth considering about buying some since they do not cost much and are extremely useful.
