Relic Hall

Relic Hall is one of the most significant buildings in Castle Clash where you can buy the Magic Spells and can upgrade them by using Gold or fastest by using Gems. These Spells provide the Heroes’ stamina & keep them healthy that is why the heroes get advantage in Raids and Dungeons. There are four types of Spells, a clasher can use it up to 4 spells but it depends on the level of Relic Hall. Step by step, have to upgrade each spell. There is a Replenish icon with it you can auto buy all spells at a time. If that time you buy wrong spell then you can also cancel and get back a partial refunding.

The Spells’ description and usability describes with this table. (Source: Relic Hall of Castle Clash)

Spell	Description	Usability
Arrow Rain	Rains arrows on an area, dealing 8% of Max HP + 120 DMG to all enemy troops within the area over 8 seconds. Does not affect buildings.	This spell is useful for low might players to clear troops out of army camps. It’s damage is quite low however so you should not use this against heroes because they generate energy each time it hits them.
Restoration	Places a healing circle on the battlefield, healing all friendly troops in the area for 6% of their Max HP + 10 HP every second for 8 seconds.	This spell is powerful for players at all levels. Level 5 can heal 120% HP + 400 over 8 seconds.
Ares’ Fervor	Invokes Ares’ strength on all your troops and heros, granting them +5% ATK until the battle ends.	The spell affects troops and heroes deployed before the magic is cast. Level 5 increase ATK by 17% and it is quite useful for early game raiding. Long term this spell isn’t overly necessary however.
Windstorm	Sweeps a hurricane through the enemy base, dealing 8% Max HP +800 DMG for 8 seconds to all enemy buildings in it’s path. Tilt your device to control the storm’s path.	Windstorm affects buildings only and is useful to hit and run vaults that are out of reach.
Guardian Angel	Summons an Angel’s protection, granting invulnerability to a number of friendly troops (including heroes) in the area for 6 seconds.	Guardian Angel is an extremely powerful spell.  At level 1 this spell protects all of your heroes so it is best NOT to upgrade it as to keep its cost low. Good timing with this spell will allow you to decimate bases while raiding at all might levels with any heroes. Watch the videos on raiding to see its effectiveness.
Meteor	Showers an area with meteors, dealing 12% of Max HP as DMG to all enemies in the area for 6 seconds.	Meteor is essentially an upgraded version of Arrow Rain but cannot kill heroes. This spell therefore isn’t overly useful.
Disaster	Rolls a massive boulder across the battlefield, dealing 10% Max HP +300 DMG for 5 seconds to all enemies in its path. Also reduces ATK of affected troops by 20% for 5 seconds. Tilt your device to guide the boulder.	Better than Meteor and debuffs but still seems to lack the effectiveness required to justify using it over the very powerful spells available.
Ares’ Frenzy	Ares’ bloodlust possesses friendly troops (including Heroes) in an area for 8 seconds, granting +20% ATK, ATK SPD, and MOV SPD.	Ares Frenzy is an extremely powerful spell, it is a Pumpkin Duke proc in spell form. At level 5 it gives a 60% boost and used in combination with pumpkin Duke and powerful heroes it can allow you to level bases in second.
Phoenix flight	Summons a Phoenix that flies across the battlefield for 10 seconds, randomly reviving 6 friendly troops in it’s path (not Heroes). Guide the Phoenix by dragging your finger on the screen.	Phoenix Flight revives troops only which may make it quite powerful if future updates make troops more effective.
Snowstorm	Blankets an area with a snowstorm, dealing 6% of Max HP +200 DMG to all enemies in the area. Also freezes affected troops for 6 seconds.	Snowstorm is quite powerful. Due to it freezing all targets within range it is a very useful tool when raiding to give your heroes the drop on theirs. it also shuts down towers within range.

Relic Hall is an important part in the game by which your heroes can play better. As an expert, I can say that the magic Spells are another life blood for the heroes in Raid & Dungeons. So, make sure your heroes life secure by leveling up the Relic Hall & it’s contains Spells.

Thanks.
