Confused about mage skill

Can anyone explain me the difference

1. Between arrow, javelin, and lance ( since they are single target)
2. Between wall and blast ( since they are aoe)

Please Explain to me all of them, in term of damage, usefulness, best for bossing or farming, effectivenes, cast time, or any other thing you might know

Sorry for bad english

 

Magic wall is just like a wall you cast it and then the mobs run into it and die. Magic blast well.. idk how other people even find it usefull the damage is great but the slow cast time ruins it. Javelin is like a mini version of magic blast with faster cast time and its single target.. Better get that than magic blast. Lances is like a upgraded version of magic arrows but longer cast time and higher damage. Go check out my mage guide if you need help with mage skills or stats.

 

Personally at this stage I don't see the use in either. I use lv5 wall and lv10 arrows and I have yet to find my damage lacking. If anything its the opposite, I'm constantly reigning my damage back for breakers with the exception of bosses like giant boar, and for those I'm healing and letting other dps like archers and brawlers do the heavy lifting and occasionally casting an arrow or two.

For Blast its even more so. I could see it maybe for solo builds if you did a wall/blast combo to buy yourself the cast time, but tbh I only ever use my wall for farms, and once in a blue moon to get a boss off me for mp recovery. If you're in a party and needing to use wall a lot, you don't need an upgrade, you need a new tank.

 

@Faust ty for your advise @garou ty for your advise
I find my self using this combo
1. When i have tank or breaker ( best dps)
Set skill arrow-wall(smite)-charge
2. When i have no good tank or breaker ( lower dps but i can maintain the distance to boss)
Set skill arrow-lance (smite)-charge

I upgrade chaincast lvl 5
Set lance / wall after arrow make cast time for lance/wall significantly reduced

I dont up the magic blast yet. Still wait the next update
