[HELP]Stackable Lifestones & BOG

[Dulens.]

Hello everyone, because I don't have the necessary knowledge about system editing I want help to change the types of the lifestones and bog in order to be stackable.

 

 

1. High Grade Life Stone 76

2	8752	0	3	3	3	0	dropitems.drop_mineral_rare_m00			dropitemstex.drop_mineral_rare_t00			icon.etc_mineral_rare_i03					0	2	53	0	0	1		1		ItemSound.itemdrop_mold		0	0	0

 

2. Top Grade Life Stone 76

2	8762	0	3	3	3	0	dropitems.drop_mineral_unique_m00			dropitemstex.drop_mineral_unique_t00			icon.etc_mineral_unique_i03					0	2	53	0	0	1		1		ItemSound.itemdrop_mold		0	0	0

 

3. Secret Book Of Giant

2	6622	0	0	2	5	0	dropitems.drop_sack_m00			dropitemstex.drop_sack_t00			icon.etc_codex_of_giant_i00					0	10	18	0	0	1		1		ItemSound.itemdrop_sack		0	0	0

 

What I should change from these lines in order to make stackable these items?

 

PS; Java and database sides are ready.

 

Thanks!
