RPG Insanity

So, after I got the free Storehouse key (along ads) still on Story Quest 21, I thought my team was too weak.

I mean, because the Lottery Tickets, their weapons were already better than those of shops, they had latest armor, I used coins for the ring which blocked abnormal status and gave it to a party member, and I was happy with their level 24.

 

But I thought, “nah, this is getting boring, I don't really really like the mechanics and the music. I'll buy an Ultimate Seed or an Excellent seed to get an advantage.”

But before wasting so many points, I remembered I had a storehouse key! What could I get with it?

PS. Soul Jewel (M) gives 20 SP to everyone.

 
 

And after a while, I got an airship and visited the remaining villages.
 

This cover every town and village which you can instant-warp to it, which should also cover every storehouse, but the exact number of storehouses is not disclosed and therefore, I won't mark this list as "Complete" until I'm sure that there are no "surprise! A forgotten village!" (if you understand me).

The only items from storehouse that I used were the Star Rod and Holy Spear.  I also use the abnormal seal amulet, but you can get those in exchange for coins.   You don't need to buy seeds--use the power rebirth stones frequently dropped.  You can boost your attributes much faster and without the need for IAP stuff (but of course if you have the monster attract you can do so faster).

Well, I actually bought an Excellent Seed. Uh, my favorite char went from 100 to 1100 HP, so I guess I don't need to worry about party KO for a while xD

You see, I am lazy. There's a giantic chance that I will stop mid-way and will take months to remember of the game and having the will to resume (there are six installed games on my cellphone on that situation).

 

I plan to use my Coins and Rare Coins to first, get perfect immunity against status effects. 2 from 4 members have the ring.

Then, to get these buffs at start of battle, because usually I don't use my time buffing myself

Power Rebirth Stones are good, and I used them to beef up my other chars a little, but these seeds are much more powerful and instant.

 

...And by last, I have some IAP currency acquired by daily login bonus and fighting. I uninstall games with three digits of unspent IAP coins (and I am almost uninstalling a couple of games I've finished and already hit four digits of unspent coins), so I thought, “what a waste, why not use them?”

Unlike other games which I save IAP to unlock extra dungeons, this one only have items to make yourself stronger. Seeds were, by far, the best choice from the items, as I don't really like grinding :>

Your plan looks good and certainly a nice method if you are going to avoid grinding.  I had time to grind, so my approach was different, but your way is a good fit if you are going to juggle 6 games at once!
