Kauna :
How do you play a smn effectively in 40 cap?
Hmm, k. SMN really arent too good for low ballista caps, but i'll just answer from my own experience.
40cap i believe we have Shivas sleepga, which is awsome to have, use it when the enemy team is distracted if your team has no AoE sleepers. You calso use the popluar choice, which is Ramuh's Thunderspark. It is AoE Damage+Paralyze, really nice bloodpact.
I only go to lower caps as SMN when i want limit points lol. So i tent to have a bit of fun by using a high DMG staff with accuracy and STR gear, just for fun tho lol. And chase ppl that are dying with ur staff and fenrir.You can also sub NIN to be able to go into battle and land a nice Thunderspark w/o dying right away. But i stil prefer whm sub until uncapped, then its rdm sub.
keep these things in mind,always...
Diabolos is almost impossible to sleep, it CAN be done, but very rarely. His Absolute Terror BP is freakin nuts, not sure if its 40 cap, but in gerneral, it drains up to 4 stats from everyone near him. Nightmare is not as good as Shiva's Sleepga imo because the range and accuarcy suck ass. Camisado adds gravity effect.
Fenrir has highest DoT DMG for all avatars, meaning he hits the hardest per hit. he also has dispelga for those annoying RDMs/WHMs(i play both so i should know lol)
Leviathans tailwhip adds gravity effect. He also has slowga, not too usuful but still fun to use lol.
Shiva has Sleepga which is very nice to use on an unsuspected enemy. In 50 cap, Double Slap has done 400+ on certain jobs, really nice BP as well.
Garuda is worthless until uncapped when u start busting out 800+ Predator Claws and 1-shotting tarus and mages =O
Ramuh has 2 nice things, Thunderspark(AoE DMG+Paralyze), and Shock Strike, minimal DMG + Stun, nice to stop ppl drom getting away =O
Carby is nice in 60 cap actually lol. i make him chase a player thats almost dead, then i invis myself and follow carby, when i catch up, i land a Meteorite andet GB =)
Titan is also blah, i find myself not usuing him ver much because Earthen Ward is nice, but half the time, your team is never around for it, so it becomes a waste of MP, i prefer to sleepga or thunderspark.
Ifirt is another usless one, i never EVER use him in ballista. UNLESS theres someone wearing bombqueen ring....
Notice i tried to stay away from uncaped advice or party buffs/heals since thos are pretty much self explanitory.. if u have any more questions just ask.
