dINT=26
Look on the chart for dINT=26. Since I didn't think about WSC, I didn't see a point at which MB|SDT and SDT|MB differed, so I added a third element (MAB) to make a difference arise. Interestingly, I did not get the Magic Burst message, but the damage makes no sense otherwise (And I did it ~5x, so it's definitely landing at the right time). My guess is that if the element does not match one of the SC's element, you won't get the message, but you'll get the bonus (Fire is the only element for light SC on Bombs).
Thus far, it looks like...Code:TM Base dINT INT*TM PlusBase Bonus1 Bonus1|2 Bonus2 Bonus2|1 Difference Bonus1 Bonus2 Bonus 3 Bonus1|2|3 Bonus2|1|3 Difference 2 693 1 2 695 903 451 347 451 0 1.3 0.5 1.05 473 473 0 2 693 2 4 697 906 453 348 452 -1 1.3 0.5 1.05 475 474 1 2 693 3 6 699 908 454 349 453 -1 1.3 0.5 1.05 476 475 1 2 693 4 8 701 911 455 350 455 0 1.3 0.5 1.05 477 477 0 2 693 5 10 703 913 456 351 456 0 1.3 0.5 1.05 478 478 0 2 693 6 12 705 916 458 352 457 -1 1.3 0.5 1.05 480 479 1 2 693 7 14 707 919 459 353 458 -1 1.3 0.5 1.05 481 480 1 2 693 8 16 709 921 460 354 460 0 1.3 0.5 1.05 483 483 0 2 693 9 18 711 924 462 355 461 -1 1.3 0.5 1.05 485 484 1 2 693 10 20 713 926 463 356 462 -1 1.3 0.5 1.05 486 485 1 2 693 11 22 715 929 464 357 464 0 1.3 0.5 1.05 487 487 0 2 693 12 24 717 932 466 358 465 -1 1.3 0.5 1.05 489 488 1 2 693 13 26 719 934 467 359 466 -1 1.3 0.5 1.05 490 489 1 2 693 14 28 721 937 468 360 468 0 1.3 0.5 1.05 491 491 0 2 693 15 30 723 939 469 361 469 0 1.3 0.5 1.05 492 492 0 2 693 16 32 725 942 471 362 470 -1 1.3 0.5 1.05 494 493 1 2 693 17 34 727 945 472 363 471 -1 1.3 0.5 1.05 495 494 1 2 693 18 36 729 947 473 364 473 0 1.3 0.5 1.05 496 496 0 2 693 19 38 731 950 475 365 474 -1 1.3 0.5 1.05 498 497 1 2 693 20 40 733 952 476 366 475 -1 1.3 0.5 1.05 499 498 1 2 693 21 42 735 955 477 367 477 0 1.3 0.5 1.05 500 500 0 2 693 22 44 737 958 479 368 478 -1 1.3 0.5 1.05 502 501 1 2 693 23 46 739 960 480 369 479 -1 1.3 0.5 1.05 504 502 2 2 693 24 48 741 963 481 370 481 0 1.3 0.5 1.05 505 505 0 2 693 25 50 743 965 482 371 482 0 1.3 0.5 1.05 506 506 0 2 693 26 52 745 968 484 372 483 -1 1.3 0.5 1.05 508 507 1 2 693 27 54 747 971 485 373 484 -1 1.3 0.5 1.05 509 508 1 2 693 28 56 749 973 486 374 486 0 1.3 0.5 1.05 510 510 0
