Arch Staff of Vhenadahl

The Arch Staff of Vhenadahl is a long Iron-barked staff, strong as a chromium shield and as beautiful as a elderly willow tree. It was created during the Elven Dale dynasty, when the Prophet Syli'ra created arms for her clansmen and women using the Iron-bark trees - that only grew on the Skerries island. The staff ends with a sharp circular point - used to attack those in melee range - that holds strong and bold about half way up, before the staff begins to spiral, like two flexible steel bars. As the twists grow wider and somehow stronger, the gaps between the staff begin to glow with teal glyph seals that coil around the peak of the staff. Finally at the crown, two Perfectly crafted dragon heads at the apex, wrapped and connect together with their jaws locked around a solid diamond sphere, that holds the entire magic and structure of the staff together.

The weapon's bonus to spell attacks and damage rolls increases by  +3.

Vigorous Caster
In addition whilst attuned to the staff, you gain increased courage casting spells in the midst of combat, learning techniques that grant you the following benefits:

• You have advantage on Constitution saving throws that you make to maintain your concentration on a spell when you take damage.
•  When a hostile creature's movement provokes an opportunity attack from you, you can use your reaction to cast a spell at the creature, rather than making an opportunity attack. The spell must have a casting time of 1 action and must target only that creature.

Legendary Caster
You can take 1 legendary action choosing from the options below. Only one legendary action option can be used at a time and only at the end of another creature’s turn. You regain spent legendary actions at the start of your turn

• The creature casts a 3rd level spell or lower from it's list of spells.
•  Briefly surrounded by silvery mist, you teleport up to 30 feet to an unoccupied space that you can see.

Archonomicon
The arcane power infused within the Arch Staff of Vhenadahl, dates back to ancient practitioners of the Elven Dales. They built their arcane focus with consumable seals that enhanced the abilities of their magics. The staff powers three arcana seals around the apex of the staff. Once per turn - with these seals- you can choose one of the following enhancements to any spell the user casts;

• When you cast a spell that forces a creature to make a saving throw to resist its effects, you can spend a arcana seal to give one target of the spell disadvantage on its first saving throw made against the spell.
• When you cast a spell that forces other creatures to make a saving throw, you can protect some of those creatures from the spell’s full force. To do so, you spend one arcana seal and choose a number of those creatures up to your Spellcasting modifier (minimum of one creature). A chosen creature automatically succeeds on its saving throw against the spell.
• When you cast a spell using this staff, you can spend a arcana seal to change that damage type to one of the other listed types: acid, cold, fire, lightning, poison, thunder.

The staff regains all seals at dawn.

Proficiency with a Quarterstaff allows you to add your proficiency bonus to the attack roll for any attack you make with it.
