Dragon Invasion Guide

(This guide is brought to you by Nhock from NA-11)
=Introduction=
Dragon Invasion give you unique Rewards Star Sigil, Rare Dragon Chests and Legendary Dragon Chests. These rewards base on your rank, the higher the rank is, the higher rewards you get.
To get higer rewards, Solmyr is one of the best choice.
= Solmyr=
Solmyr is the cheapest hero to build to get the good score.
Requirement: you must have 2 Stars Solmyr for the Electrostatic Field effect. 
==How to cast spells==
Main damage source of Solmyr come from his 2 stars effect Electrostatic Field, so you need to cast as many damage spell as posible to trigger that effect. Remember: Only Damage Spell of hero will trigger the effect, so Wind Wall can not trigger that effect.
 
Use all spell except Wind Wall on the dragon. You can cast Wind Wall on Giant (if you have) to trigger his awakening skill, but this is not the top priority. You need to keep enough mana to cast other spell as soon as posible.
If you have Sword of Frost, cast it first.
If you don't have enough mana, focus on Air Arrow and Lightning Bolt first, try to cast them immediately after cooldown. You can cast Chain Lightning when baby dragon appear.
If you have Storm as a spell mark, you can ignore Chain Lightning and cast Storm instead.
===Recommended Mastery===
Those three are actually competing for the best mastery for Solmyr.
Air Magic decreases cooldowns which allows to cast him spells faster. 
Mysticism mastery increase mana regen so Solmyr can cast more spell.
With Wisdom all your spells gain 3 levels, which as a consequence leads to more spell damage without increasing their cost.
The last is Sorcery. Since most of units in the team will be caster, This mastery will help to increase the damage, especially when you have Giant.
===Recommended spellmark===
As I mentioned before, main damage source of Solmyr come from his 2 stars effect Electrostatic Field and it can only be trigger by Air damage spells. This mean Storm is the best spell mark for Solmyr at the moment.
Air Mastery can be a good choice too.
=Recommended Units=
These units are very good in Solmyr team
*Monk: increase mana regeneration.
*Firebird: 5 more seconds to cast spell.
*Mage: recover mana when cast air spell, and give Static effect.
*Storm Elemental: increase initial mana, and give Static effect.
*Ice Elemental: increase mana regeneration.
*Roc: reduce Magic Resistance of the enemy. You need Shiva 3s for this effect, otherwise don't use Roc.
These units will increase your score alot and good in any team.
==Recommended Awakening Skills==
Firebird: Endless Storm, Lava Breath, and Endless Rage.
Mage: Magic Mastery, Arcane Node, Energy Suppression.
Roc: Thunderstorm, and Electric Shock.
==Recommended emblem==
 
Monk, Mage Storm Elemental and Ice Elemental are good in Solmyr team because their skill give Static effect or increase mana effect. That make Everlasting Secret will be the best emblem for them. It will increase skill level which will increase those effect as well.
In the case of Devil, his damage com from Withering, so Everlasting Secret will help to increase the damage deal by this skill.
Tips: 
*4-set effect is enough, you don't need to go for 6-set effect for those units.
*If you don't have too many Everlasting Secret emblem, you should focus Storm Elemental and Mage first.
 
Giant and Berserker damage com from their first skill, so Anger will be the best for them.
